my parents had the greatest influence on me
as they provided the emotional and financial support to complete my engineering education
It was in their nature to help anyone around them who was in need
including extended family and local community members
This unwavering support was critical for me
especially during the difficult times in school when stress levels were high and I thought about quitting
When I started my career as an assistant professor
my department chairs and many other faculty members helped me through the challenging process of attaining tenure
Some unexpected and very valuable kindness came from professor Malcolm Nichol who was a senior faculty member in the College of Sciences
He supported my research activities early in my career even though my work was not directly related to the primary goals of his research center
He simply valued interdisciplinary work and wanted to help newer faculty develop their careers
The kindness and mentorship of others who looked beyond their own goals and needs greatly influenced my approach to work and career
innovative ideas from students and colleagues and I try to help as many people as possible further their research and discovery
regardless of whether it falls directly under my research interests or not
Brendan O’Toole received a bachelor's in mechanical and aerospace engineering
and master’s and doctorate degrees in mechanical engineering from the University of Delaware
He has been an assistant and associate professor at UNLV and now is a professor who serves as chair of the mechanical engineering department
O’Toole is one of the three co-directors of the Center for Math
and Engineering Education and serves as Director of the Center for Materials and Structures
He previously served as Director of the Mendenhall Innovation Program
He also took two leaves from UNLV to serve as a research associate for the Oak Ridge Institute for Science and Education and a senior research associate for the National Academies National Research Council

Mohamed Trabia currently serves as the associate dean for research
He has been professor of mechanical engineering since 2000 and has been involved with research efforts with a budget totaling $8 million
I was lucky to have many great teachers over the years
The one who stands out was professor Taher Awad
who taught me automatic control during the senior year of my undergraduate studies at Alexandria University in Egypt I inherited many elements of his teaching style including his willingness to pace the material based on his interaction with the students and his emphasis on ensuring that students are comfortable with fundamentals before proceeding to more complex topics
He also emphasized the practical aspects of the subject he taught
My interaction with Awad continued during my master’s studies
he spent many hours teaching me computer programming
I still use his tricks to debug computer codes
I came to know him better as a person during these years
His interest in learning about many topics outside engineering influenced me and encouraged me to try to understand other cultures and civilizations
Trabia earned his bachelor’s and master’s in mechanical engineering from Alexandria University in 1980 and 1983
He was awarded a doctorate in mechanical engineering from Arizona State University in 1987
he joined the UNLV faculty as an assistant professor
Trabia is a Fellow of the American Society of Mechanical Engineers

Bernard Malamud left his job at Nabisco in New York City in 1968 to join what was then Nevada Southern University
an 11-year-old institution that eventually became UNLV
Malamud completed his doctorate while at UNLV and taught more than 35 classes in subjects ranging from economics to management information systems to management and finance
He retired from the Lee Business School department of economics in May
and students as the rule over my 50 years at UNLV
Most memorable and appreciated was the help I received on my doctoral dissertation
The Economics of Office Location—I was ABD (All But Dissertation) when I arrived at Nevada Southern in 1968
Librarian Alice Brown guided me through interlibrary lending and helped me ferret out data from government documents
got me access to detailed New York and Phoenix office rental data through her friendships with Harry Helmsley and Del Webb
Raedeen Jacobs of the Computer Center key-punched my programs and data
particularly business college dean William T
White and mathematics professor Michael Golberg
And when the university’s 32-kilobyte computer couldn’t handle a Fortran simulation program I wrote
a brilliant math graduate student compiled it on a rusty
machine that had just been donated to UNLV by a Test Site contractor; it had previously served for weapons tests in the Pacific
These acts are far from the total sum of kindness I received from UNLV faculty and staff
but they are memories that always reminded me to extend a helping hand whenever I could to other students driven to achieve their goals
Malamud was a charter member of the first management department created in 1970
Some notable alumni of Malamud’s include: Councilman Bob Coffin; insurance executive and long-time UNLV Alumni Association president Bob Anderson; assistant dean of the Hospitality College Pat Moreo; LVCVA president Rossi Rollenkotter; and many others
He served as department chair in 1976-80 and 1996-99

Amputation is a serious threat to people with diabetes
and economic development experts is working to bring a better way to prevent the problem to market soon
Insoles developed by a team of UNLV researchers offer a much better way for diagnosing potential foot ulcerations in diabetic patients
The problem starts so small -- a little sore on the bottom of the foot
perhaps from wearing shoes that are just a bit too tight -- but in a person with diabetes it can snowball into life-changing complications
Mohamed Trabia witnessed that first-hand in his father-in-law
who struggled after complications led to his foot being amputated
That horrific result was particularly disturbing to Trabia because the method for diagnosing the problem seemed so bizarrely archaic
He likens it to feeling someone's forehead and expecting an accurate temperature reading
"It is very much 18th century thinking," Trabia said
And very much at odds with Trabia's mechanical engineering mind
He couldn't let go the thought that there must be a more precise way to detect foot problems early
In 2013, he dropped in on a tour of the Clinical Simulation Center of Las Vegas
a training facility shared by nursing students at UNLV and other state institutions
Trabia has to put in appearances at such events
and he always keeps an eye out for ways his college can collaborate with researchers in other areas
There he struck up a conversation with Dufek
a kinesiology and nutrition sciences professor
The conversation quickly reshaped their research for the next couple years
their collaboration could greatly improve the lives of millions of people with diabetes by preventing the world's leading cause of lower-extremity amputations
It may also bring new dollars to UNLV while planting a seed for the region's nascent biotechnology industry
Amputations in people with diabetes generally stem from poor circulation
which leads to a loss of sensation and tissue stiffening
Diagnosis involves running a light filament wire along the bottom of the foot wire to gauge a person's level of foot sensation
is too reliant on how hard the doctor is pushing the filament
the doctor's awareness of the situation at that particular moment
and the patient's willingness to share information
an expert on the mechanics of walking and running
was very familiar with performance-enhancing insoles on the market today that use sensors to analyze and correct an athlete's gait
Why not create insoles that offer people with diabetes and their doctors feedback about potential problem areas
Monitoring individuals over time would help determine if their tissue stiffness has increased to an unhealthy level where foot ulcerations may occur
Their idea is to use the pressure-sensing insoles to monitor the changes of the plantar tissue stiffness and collect the information through a smart phone app or other device
"We want to be able to predict where (an ulcer) is going to happen so the physician and patient can work together to prevent it from occurring," Dufek said
a mechanical engineering graduate assistant
the researchers focused on making sure the data collected by the insoles is accurate and consistent
the team has tested the insoles on 30 healthy people
Next they plan to gather data from pre-diabetics and diabetics with and without ulcers
the team can develop a "stiffness model" with algorithms that help a physician accurately assess if a patient's tissue stiffness is reaching a dangerous level
and finding what normal tissue stiffness is for any given person can be a huge challenge
and the same person can walk differently from one time to another
The way a person walks directly relates to the amount of pressure being applied to sections of the plantar tissue
and the changes in pressure as a result of different gait patterns
can impact the professors' insights into how normal tissue stiffness should behave
Mechanical engineers like Trabia are usually concerned with the properties of manmade materials
he's analyzing the characteristics of the plantar tissue
"Then (we're) creating a mathematical model to describe the tissue behavior," Trabia said
The work comes with plenty of trial and error
It requires both Trabia's deep engineering knowledge and Dufek's insights into the human anatomy
"Every step is error-producing and error-correcting," Dufek added with a laugh
"We're a complementary team in that we both have unique strengths
We really can't do this without each other."
Nor can they take their idea to market without reaching out beyond their labs
"So how do we balance academic research objectives of furthering knowledge and publication on one side with making some connections with business if we want the idea to grow?"
UNLV has been ramping up efforts to foster the commercial development of the ideas that faculty and students develop
Among its successes have been the Lee Business School's new entrepreneurship programs
which immerse students in the process of launching new businesses
In fall 2014students researched about 50 presentations to assess the commercial viability of the projects
these students create the plans necessary to attract investor funding and launch businesses around the ideas generated on campus
The insole idea struck a chord with John Landrith
an undergraduate taking the class and computer network engineer who has owned his own businesses
"My mother died from diabetes complications and the potential to make a difference in people's lives really drew me to this," he said
Landrith teamed with graduate students Peter Puglisi
and graduate certificate student Christine Nolan to create Mov?oMedics
the business entity charged with the challenge of commercializing a technology still very much in its infancy
The next big step is identifying funding sources for the new venture
"We know that it's very early stage but we're ready for the challenge associated with technology hasn't been proven yet."
Mov?oMedics has won the Southern Nevada Business Plan Competition
the state's Governor's Cup business plan contest
and is competing in the Tri-State business plan competition on May 27
"Competitions are a quick way to get funds at this point," Landrith added
and understanding of the product are all insanely detailed
and that's why we're winning these competitions."
The team envisions selling or leasing the insole package to doctors
It would include six sets of insoles in the most common American foot sizes
Mov?oMedics would then provide a precise measurement of the patient's tissue stiffness to the doctors
Not only would patient outcomes be much improved
the new equipment will ultimately save money
The doctors would recoup the costs of the equipment through insurance reimbursements while the cost of the new test for insurance companies would be comparable to the existing exam
Insurance companies would see a huge savings by avoiding amputations
which can run between $75,000 and $150,000 per person per amputation
executive director of UNLV's technology development and transfer office
said the Mov?oMedics effort is an example of increased focus throughout the university in supporting state economic development efforts
bringing to market the intellectual property discovered on campus
"We look at these things and try to see if there's a market
then we'll engage external counsel to file a patent," Miles said
"(Mov?oMedics) was a great opportunity to get students to see if they can build out a business case behind the idea -- and they sure did."
The technology transfer office team has increased patent filings from five in fiscal year 2012 to 28 patents in fiscal year 2014
about half the patents the office has helped file are gaming-related while the other half has come from science and engineering research efforts
The launch of UNLV's School of Medicine will exponentially increase patent output
Miles' team also connects the campus to the dozens of regional business leaders and entrepreneurs on its Technology Advisor Committee (TAC)
His team also is building its programs to tie into efforts in the Governor's Office of Economic Development and the Las Vegas Greater Economic Alliance
Making a big splash at business plan competitions is a great first step
but there's still plenty of steps ahead for Dufek and Trabia
They must amass massive amounts of data to develop the insole
the pair is trying to balance their research with their desire to teach and mentor students
but we are trying to support a small cadre of young
promising academicians who can learn from the process," Dufek said
As Landrith's team is pursing private funding options
Dufek and Trabia are applying for federal research grants to support the work
Grant-funded research is a major part of UNLV's drive to become a top-tier university while increasing its economic impact in the community
And the medical school opening will only enhance UNLV's current biomedical research and bring further opportunities for collaboration across disciplines
working to bring outside sources of money to UNLV to allow us to free time and focus on this," Dufek said
The Mov?oMedics business plan estimates about $700,000 is needed to get from the current data collecting point to a prototype
Another $5 million would be needed to get it through FDA approvals and advanced testing
followed by a marketing ramp up into sales distribution
Landrith estimates that process will take about two and half years once funding has been found
Translating solid research into a new company is seldom a simple process
"But there are so many groups you have to engage --business leaders
it takes an entire team to translate the technology from an answer to a question to a viable product."
But that's not stopping the Mov?oMedics team
The group has been reaching out to different CEOs and venture capital entities that have taken products through the FDA process
They used prize winnings and connections gained through networking to find an FDA consulting firm
And they've started tapping into the all distributors
They also reached out to the University of Utah spin-off
which has developed an insole that can help correct walking problems
for mentorship and to explore business partnership opportunities
As the project moves from idea to prototype
the process will involve people from a variety of disciplines
from both the business development and data collection standpoints
"If we don't have interaction with medical professionals
it can be a very clever idea that will not go anywhere," he added

Development of biomimetic actuators has been an essential motivation in the study of smart materials
few materials are capable of controlling complex twisting and bending deformations simultaneously or separately using a dynamic control system
we report an ionic polymer-metal composite actuator having multiple-shape memory effect
and is able to perform complex motion by two external inputs
Prior to the development of this type of actuator
this capability only could be realized with existing actuator technologies by using multiple actuators or another robotic system
This paper introduces a soft multiple-shape-memory polymer-metal composite (MSMPMC) actuator having multiple degrees-of-freedom that demonstrates high maneuverability when controlled by two external inputs
These multiple inputs allow for complex motions that are routine in nature
but that would be otherwise difficult to obtain with a single actuator
this MSMPMC actuator is the first solitary actuator capable of multiple-input control and the resulting deformability and maneuverability
Most actuators contain mechanisms that have large size and complex structures
their application is limited with regard to small-sized robots
undesired motor noise could be produced when operating the system
(a) An IPMC sample in the evaporating pan
(b) A scanning electron microscopy (SEM) image of a cross-section of IPMC
The IPMC consists of the electrode on both sides and the polymer membrane between them
(c) An illustration of the IPMC operating principle
Deformation will occur if an electric field is applied across the IPMC
which causes the ions to redistribute along with the water molecule
The size of the IPMC is 50.78 mm in length
(d) Continuous deformation of IPMC in one cycle under the voltage of 2.6 V amplitude and 1 Hz frequency
and displacement of IPMC versus time under the above voltage input
99.87 mm in length and 0.95 mm in diameter
were programmed with loops having different shapes wrapping around a metal rod in the water
was wrapped and programmed at 85 °C and fixed at 75 °C to achieve the first programmed shape
respectively by wrapping around the rod with different cycles
which are electro-mechanical and thermo-mechanical actuation effect
the MSMPMC can perform deformation with multiple degrees of freedom
Several shapes can be programmed into MSMPMC material memory at various temperatures
which enables thermo-mechanical actuation effect
This type of actuator demonstrates high maneuverability by controlling two external inputs – electrical input and thermal input - allowing the complex twisting
and oscillating motions that are frequently observed in nature-made systems
Through the electro-mechanical actuation effect
the actuator is able to perform high-frequency bending motions under external electrical input
With the thermo-mechanical actuation effect
complex motion under external thermal inputs
Compared with the electro-mechanical actuation effect
the thermos-mechanical actuation effect occurs over a much longer timescale
The ability to control MSMPMC actuators by two external inputs
enables these devices to be used to perform highly complex motions
bending and oscillating simultaneously or separately
The twisting and bending motions are induced thermally and the oscillating motion is induced electrically
The bending motion and oscillating motion take place with the same rotation axis; previously
this could be realized only with existing actuator technologies by using multiple actuators or another complicated robotic system
the MSMPMC actuator presented in this paper is the first solitary actuator capable of multiple-input control and the resulting deformability and maneuverability
The tip of the MSMPMC was painted white to facilitate image analysis
A side line was painted on the MSMPMC to distinguish the deformation
(b) The first shape of the MSMPMC was programmed by heating at 85 °C and cooling at 70 °C
The MSMPMC was wrapped around a rod during the programming
(c) The second shape of the MSMPMC was programmed by heating at 60 °C and cooling at 22 °C
The sample was under a sinusoid AC voltage of 3.7 V initial amplitude and 1 Hz frequency
The water was heated from 22 °C (room temperature) to 90 °C
oscillation of the actuator was noticed under the applied voltage
The MSMPMC gradually bent from the left side to the right side
To measure the 3D deformation of the actuator
Three points were tracked at two corners and the middle of the actuator tip
(a) 3D position track of MSMPMC actuator
The applied sinusoid AC voltage has 3.7 V initial amplitude and 1 Hz frequency
The measured temperature increased from 34.9 °C to 84.3 °C
(a) Bending displacement and temperature of MSMPMC versus time under an external electrical input of 3.7 V initial amplitude and 1 Hz frequency and thermal input from 34.9 °C to 84.3 °C
(b) Twisting angle and temperature of MSMPMC versus time under external electrical and thermal input
Along with the bending motion, a twisting motion was performed by the MSMPMC. Figure 6b shows the twisting deformation of MSMPMC
The twisting angle was obtained by calculating the angle difference between the two end lines of the MSMPMC
As the temperature increased from 34.9 °C to 84.3 °C
the MSMPMC twisted by 36.6° due to the thermo-mechanical actuation
the electro-mechanical actuation effect resulted in an oscillation
(a) Measured voltage response of MSMPMC versus time
The initial amplitude of sinusoid voltage input was 3.7 V and the frequency was 1 Hz
(b) Measured current response of MSMPMC versus time
(c) Electrical impedance of MSMPMC versus temperature
experiments were conducted to obtain the fixity and recovery rates of the MSMPMC
The MSMPMC was bended by wrapping around a cylinder
The programming process is the same as previous
The first programmed shape S1 was programmed by heating to 85 °C and cooling to 70 °C
The second programmed shape S2 was programmed by heating to 60 °C and cooling to 22 °C
The MSMPMC recovered from S2 to S1 upon reheating above 70 °C
The deformation of the MSMPMC was measured through image analysis and the strain was derived based on the deformation
By comparing the strains of fixed shape and programmed shape
the fixity of S1 and S2 are obtained as 96.86% and 80.19% respectively
Through comparing the strains of programmed shape and recovered shape
the recovery rate of S1 is obtained as 89.83%
Based on Fig. 7
it was found that temperature had an influence on the electro-mechanical actuation effect of the MSMPMC
The resistance of the MSMPMC decreased as the temperature increased
This property could be applied on the thermal feedback of the MSMPMC
By measuring the input voltage and output current of the MSMPMC
the temperature of the MSMPMC actuator could be obtained
Within the range of the broad glass transition temperature
the Nafion™ could be programmed with multiple unique shapes
and recovered under different temperatures
complex shape change of the actuator could be achieved with thermal control
and the thermo-mechanical actuation could be used for overall structural deformation
the MSMPMC could perform an oscillation motion by applying voltage on the surface electrodes
The actuation amplitude and frequency of the oscillation could be adjusted by changing the amplitude and frequency of input voltage
the electro-mechanical actuation of the MSMPMC could be utilized for locomotion
a MSMPMC actuator with complex deformation capabilities was developed
The MSMPMC could be controlled separately by means of thermal and electrical inputs
It had the advantages of resilience and inherent softness; moreover
the electrical characteristics of the MSMPMC changed as the temperature changed
it could be applied to medical devices and biomimetic robotics
bending of the tube-shaped IPMC was limited due to the stiffness of the tube
new catheters can be fabricated with large deformations of multiple degrees of freedom
a capability that can be utilized in complex vessel networks
A flexible heating wire will be inserted inside the catheter for thermal controlling
A layer of thermal insulation film will be covered on the surface of the catheter to insulate the heat conduction between the body and the catheter
The experimental setup used for measuring thermal and electromechanical responses of the MSMPMC actuator
where L is the length and δ is the tip deformation of the MSMPMC
By relating the radius of the curvature ρr to strain ε
The fixity can be obtained by comparing the strains of fixed shape εf and programmed shape εp
The recovery rate can be obtained by comparing the strains of programmed shape εp and recovered shape εr
the videos from the two cameras were analyzed to measure the twisting angle and the bending deformation of the MSMPMC
the image analysis program was calibrated to a set coordinate frame
This was done by creating a coordinate frame specifically for the volume of space that the tank of water occupied
The videos were analyzed in the program along with the calibration coefficients file
Three points at the free end tip were tracked in the videos to determine the deformation and twist of the MSMPMC
To calculate the bending deformation of the MSMPMC
Yu of the MSMPMC fixed end were measured as and
which was in the same horizontal platform of Xu
Assuming the projective point of Zu on line XuYu is Au
can be obtained by solving the following equations:
Line XuYu and line ZuAu were orthogonal to each other
and line ZuAu was in the thickness direction of the MSMPMC in a neutral position
By calculating the projective point of the MSMPMC tip point on line ZuAu
the bending displacement of the MSMPMC could be obtained
Assuming the coordinate of tip point Zd was
the coordinate projective point Ad on line ZuAu could be obtained by using the following equations:
The twisting angle θ could be obtained by calculating the angle difference between vector XuYu and vector XdYd:

“There are concerns about the validity of the warrant that has come before the court.”

The migration route from North Africa to Europe remains one of the deadliest and most dangerous routes for children
detention and separation from family are serious risks that migrant children face.
UNICEF Executive Director, Catherine Russell
stresses that this high number of innocent children losing their lives in the hope of a better future together with their families demands an immediate effort from all
This is why it is important for governments to fulfill their international obligations under the Convention on the Rights of the Child
which include: protecting the rights and best interests of children; providing safe and legal migration routes; strengthening the coordination of search and rescue operations and national child protection systems to avoid exploitation and violence; improving life prospects in the country of origin and ensuring that children have access to information to make informed choices.
UNICEF underlines that the European Union must also ensure the above through the European Pact on Migration and Asylum currently under negotiation

A Sicilian mafioso fighting extradition to Italy after living quietly in Britain for two decades under an assumed name was denied bail yesterday in a London court
who was known to his neighbours in the London suburb of Uxbridge as Marc Skinner
was described in court as “one of the heads of an armed criminal organisation known as Cosa Nostra”

After concerns were raised about the warrant, Italy issued a new one yesterday and he was re-arrested on court premises
Nicknamed “u Profissuri” (the Professor) in Sicilian dialect
former boss of a Mafia clan in Trabia near Palermo
Prosecutor Benjamin Siefert said Domenico Rancadore had been tried in his absence in Italy and convicted to seven years in prison over Mafia activities from 1987 to 1995
“Mr Rancadore was considered a ‘man of honour’,” Siefert told the court
Quoting from the warrant issued by a prosecutor in Palermo
Siefert said Cosa Nostra was “made up of thousands of members spreading terror in Sicily..
and systematically murdering anybody who did not comply with the will of the members of the organisation”
He said that Rancadore had been in charge of a territory around Trabia and had ensured strict compliance with Cosa Nostra rules in the area
grey-haired Rancadore sat with his arms crossed in the dock
shaking his head as the prosecutor spoke and making frequent eye contact with his wife and daughter
said Rancadore had arrived in Britain with his wife Anne
The family had been settled in their semi-detached suburban home in Uxbridge for the past 13 years
Macmillan said the property was worth £300,000 (€349,000) and Uxbridge was “not a luxurious address”
The lawyer said the family had chosen to use the wife’s family name
and that Rancadore “did not go out much”
Judge Quentin Purdy denied him bail
telling him that he had “actively evaded apprehension for a significant period” and that “police have had some difficulty in tracing you”
Rancadore was remanded in custody until the next hearing

A town in Italy is selling old, abandoned properties for only $1.60 (about one Euro), but there is a catch! Obviously, these homes are not in great shape and would likely cost a lot to renovate. If you buy one of these homes, you must agree to renovate it within a year
you lose your security deposit which could be around $8,000
you have to give an $8,000 security deposit when purchasing one of these super cheap homes
Reportedly there are also administrative fees which can cost you around $4,000 to $6,450
Another town in Italy tried this with great success
offered this deal to hopefully get rid of abandoned homes and add new residents
These small towns are becoming abandoned because many Italians are moving to bigger cities
Currently, there are around 100 abandoned homes for sale but that number could go up to 500! If you love to renovate homes and have always wanted to live in Italy, this might just be a good deal for you. This honestly sounds like a great HGTV show!
When looking at the website for more details
it looks like it will become a television show
“Ever fancied your very own place in the sun but never quite within your reach
This Sicilian town of Mussomeli is giving you the chance to buy a historic home for just ONE EURO.”

or a restoration novice in the market for a holiday home we want to follow your story as you FOLLOW YOUR DREAM.”
Sambuca’s deal was similar but had different fine print
you had to agree to invest $17,000 over a three-year period to fix up the home
you have more time but you also have to agree to invest way more cash
This is just a reminder that if something sounds too good to be true (for example, a home for sale under $2), it probably has a lot of fine print. However
it could be a great opportunity for some people
