    Breast cancer is one of the major malignant tumors threatening the health of women. With the changes in people's lifestyle and diet, the incidence rate of breast cancer continues to rise all over the world. Despite the considerable progress in conventional cancer therapies such as surgery operation, radiotherapy, chemotherapy and incretion therapy, the intrinsic limitations of these therapies such as drug resistance still make the therapeutic effect dissatisfactory. In this study, nude mice inoculated with human breast cancer cell line MCF-7 were treated by nanosecond pulsed electric fields (nsPEF), a novel promising technique in cancer therapy. High frequency electromagnetic field distribution of the parallel plate electrodes was simulated by Ansoft HFSS software. The average tumor volumes in treated group almost stayed the same after 10 days, but in control group the volumes increased to 8 fold larger. The typical structural changes of the tumors after nsPEF treatment were observed in vivo in a 3.0T clinical magnetic resonance imaging (MRI) system with an own-made animal-used radiofrequency coil. High quality images were achieved to evaluate the contrast from control and treated group. Other MRI technologies in clinical cancer diagnosis will be potentially used to investigate the changes in tumors. Immunohistological tests indicate significant inhibition in tumor growth after nsPEF treatment. Thus nsPEFs can serve as a drug-free treatment for breast cancer, which may have potential applications in clinics. View full abstract»

    Service projects offer volunteer student organizations a means to generate interest and focus activity outside of the context of the classroom. This paper addresses efforts by the Kansas State University (KSU) Student Chapter of the IEEE Engineering in Medicine and Biology Society (EMBS) to initiate and guide service projects in two primary areas: (1) research to aid persons with disabilities (RAPD) and (2) hands-on efforts to interest young women in the quantitative fields of science and engineering. Three RAPD projects are presented: a computer mouse design that helps to alleviate productivity problems associated with Parkinson's tremors, a battery removal tool for arthritic individuals with limited dexterity, and a wireless door control and communication system to assist mobility-limited individuals. Service projects to garner science and engineering interest in young women are co-sponsored by the KSU Women in Engineering and Science Program (WESP). The most recent activity, entitled “Vital Signs Shirts,” is presented in this paper, along with a summary of pending interactive laboratories designed to interest participants in engineering as applied to the human body. These service projects encourage IEEE EMBS student chapter members to explore their biomedical engineering interests and make a positive impact in the community. View full abstract»

    Sensor networks offer a powerful combination of distributed sensing, computing and communication. The distinguishing traits of sensor networks have a direct impact on the hardware design of the nodes at various levels: power source, processor, communication hardware, sensor nodes and actuation components. Sensor networks are also widely applied in habitat monitoring and agriculture research. An integrated network of sensors combining on the ground sensors monitoring soil moisture levels, humidity, temperature, plant growth, ground water level, disease identification together with Global positioning system facilities and long term field monitoring to absorb the variations in the agricultural field will enable the determination of risk levels in targeted regions as well as valuable information on agricultural development. The overall goal of the research and development effort described in this work is to devise an integrated system in the form of plant growth monitoring and control system comprising a distributed network of sensors for sensing the plant growth activity, drip water irrigation, temperature sensing, ground water monitoring and environmental conditions to improve the productivity in agriculture.

    This study investigates the validity of the Westervelt equation for focused transducers. The angular spectrum method is employed to analyze the second-harmonic acoustic field under the weakly nonlinear approximation. Although it is well known that the Westervelt equation is accurate for the case of quasi-plane waves, the present work demonstrates accurate solution for the highly focused case of a spherically-curved ultrasound transducer having an aperture angle of 80°. It is further found that the solution error is inversely dependent on the nonlinearity coefficient. View full abstract»

    Women are under-represented in technology- intensive fields. A possible cause might be gender differences. Men and women have differing approaches to communication which persist in the virtual world of online education. A second possible cause is gender discrimination. In male-dominated fields such as engineering, this difference can result in men discounting the contributions of their female classmates, thus creating a chilling effect. Communication in an asynchronous learning network (ALN) is different from face-to-face communication. Incorporating asynchronous communication elements in a technology-intensive class presents the potential to create an environment that could be more amenable to the woman student. Creating an environment that engenders social presence could make the class more amenable to the learning needs of the woman student. This research reports on a study with doctoral level students in both a technology intensive class and a more people-oriented class. The results of the study indicate that although both men and women registered the same degree of social presence regardless of the type of class, the technology-intensive classes displayed significantly less social presence unless assignments were structured to specifically promote that type of interactivity.

    Universal Serial Bus (USB) is a new personal computer interconnection protocol, developed to make the connection of peripheral devices to a computer easier and more efficient. It reduces the cost for the end user, improves communication speed and supports simultaneous attachment of multiple devices (up to127)RS232, in another hand, was designed to single device connection, but is one of the most used communication protocols. An embedded converter from RS232 to USB is very interesting, since it would allow serial-based devices to experience USB advantages without major changes. This work describes the specification and development of such converter and it is also a useful guide for implementing other USB devices. The main blocks in the implementation are USB device, UART (RS232 protocol engine) and interface FIFO logic. The USB device block has to know how to detect and respond to events at a USB port and it has to provide a way for the device to store data to be sent and retrieve data that have been received UART consists of different blocks which handle the serial communication through RS232 protocol. There are a set of control registers to control the data transfer. The interface FIFO logic has FIFO to bridge the data rate differences between USB and RS232 protocols. View full abstract»

    This paper presents the development of a wireless sensor network which is deployed for the purpose of analyzing the strategy for field hockey. The indoor cricket location system has been used to acquire the location of a particular sensor node known as the listener. A review of the existing strategic systems utilized by the national coach of the Malaysian women's hockey team is provided to complement the design and motivation of this project. The review and analysis was done during the participation of the Malaysian women's hockey team at the Olympic Qualifier in Victoria, Canada. The visualization of the application for the purpose of analyzing the wide-spectrum of probabilities in player movement has been done using OpenGL. As an initial stage of the experiment using the cricket indoor location system was used to acquire the pre-defined coordinate system. The obtained results have enabled a dynamic strategic planning to facilitate the strategy planning which captures the essence of the human tracking and cohesively harnesses the reconfiguration elements of wireless sensor networks.

    Micro electromechanical systems (MEMS) are small integrated 3 dimensional devices having structures ranging from sub micron level to millimeter level that combine electrical and mechanical components on a single substrate. They find various applications in mechanical, optical and biological fields due to a reduction in size, the excellent mechanical properties of silicon, extension of the well developed designing, fabrication and packaging processes of the Integrated Circuit (IC) industry, cost effectiveness etc. The special feature of a smart MEMS sensor is the ability to integrate sensing, controlling and actuating functions on a single chip. In this paper various factors which play a critical role in the performance of a MEMS pressure sensor diaphragm are discussed. Various parameters like side length, radius, and maximum stress induced in a square and circular diaphragm are calculated for a pressure range of 0.1 to 1MPa. The effects of variations in the applied pressure on the geometry of the sensing element and the relationship between applied pressure, the induced stress and the dimensions of the micro sensing diaphragm are discussed using the WEKA data mining tool.

    Burn-in is a widely used engineering method to eliminate defective items before they are shipped to customers or put into field operation. Burn-in procedures are usually applied to items with high initial failure rate which operate under a static operational environment. In this paper, we consider burn-in for items that operate in an environment with shocks. We assume that there are two competing risk causes of failure: the `usual' degradations, and environmental shocks. A new type of burn-in via controlled (laboratory) test shocks is considered, and the problem of obtaining the optimal level (severity) of these shocks is investigated. Furthermore, we combine the conventional burn-in procedure with burn-in via shocks in one unified model. View full abstract»

    In a variety of signal processing applications, nowadays, the use of radar for advanced control has become a necessity, e.g., navigational systems, aircraft, automobiles and other sensing devices. A normal microprocessor based radar signal processor eats a lot of processing power and time so we have proposed the implementation of a dynamically reconfigurable pulsed Doppler radar in a mixed system comprising a digital signal processor (DSP) and FPGA to perform linear frequency modulation, Gaussian noise filtering, downconversion, pulse compression (matched filtering) and pulsed Doppler processing. Allowing the users to modify range and delay, the reconfigurable processor on-chip helps DSP(s) exploit more of the parallelism found in digital signal processing applications, thus improving the processor's overall performance.

    This paper presents a resource discovery scheme for decentralised unstructured P2P file sharing applications. The scheme utilises the principles underlying elephants migration from dry place to green fields for food. Hence, the proposed approach is a bio-inspired swarm intelligence based search technique. The aim of the technique is to route a query from a node to suitable peers in the network to find the required object. For this, the scheme divides the resource available areas in the network as wet areas and dry areas. The wet areas are resource fertile areas and dry areas have very limited resources. When a node is located in a dry area, its queries are propagated to wet areas for increasing the performance of resource discovery process. At the same time, the powerful nodes try to make the dry area into a resource lush one so that nodes that have moved to wet area return home for resource discovery. Simulation results show that the proposed scheme significantly increases query success rate and reduces the network traffic as the resources are effectively distributed to well-performing nodes.

    This paper presents a hybrid system controller, incorporating fuzzy controller with vector control method for induction motors. The vector-control method has been optimized by using both PI and fuzzy controllers. This combines the benefits of fuzzy logic controller and vector-control in a single system controller. High quality of the regulation process is achieved through utilization of the fuzzy logic controller, while stability of the system during transient processes and a wide range of operation are assured through application of the vector control. This paper also deals with the speed estimators for applications in sensor less induction motor drive with vector control. In the present work, Indirect vector controlled induction motor sensor less drive with PI and Fuzzy controllers is implemented. It shows that the performance is better for fuzzy when compare to PI controller. View full abstract»

    In India a good number of women workers, engaged in small scale industries, perform various tasks in a squatting-on-the-floor posture. Sometimes they use a patla (wooden plank) for sitting. Most of them suffer from severe cervical and lumbar joint problems along with knee and hip joint pains, as evident from their medical reports. To understand whether the continuous sitting-on-floor posture is the culprit for this kind of problem, and whether it can be rectified, a study was conducted with an aim for better designing of work stations for small scale industry. The study examined the work posture of 75 women workers (experimental group) engaged in a small scale industry performing the task of sorting, inverting and packing socks. The worker women had to maintain a constant seated position (squatting cross-legged) on the floor. Along with the worker group, an equal number of housewives belonging to the same socioeconomic status were also studied as a control group, these women never acquired such kinds of postures for prolonged periods. To ascertain the effect of work posture both qualitative and quantitative assessment procedures were followed for both the groups. The qualitative evaluation, which consisted of a questionnaire and direct observation, revealed that long term seated work had a cumulative load on the musculoskeletal structures, including the vertebral column which was reflected in the form of high prevalence of discomfort and pain in different body parts. The quantitative methods were grouped under the following headings, namely: anthropometric, biomechanical, physiological and psychophysiological issues. The methods were used both in the field and in laboratory studies. With the help of a simulated laboratory setup, using a forward-downward sloping patla with an adjustable top surface, it became evident that an angle around 12° of forward-downward slope was the most comfortable angle from the viewpoint of the electromyographic responses of the postural muscles and the worker's comfort. A significant shift in the centre of gravity location towards the body was observed with the increment of the seat angle, which may be the reason of reduced postural muscular activity resulting in better comfort View full abstract»

    Incontinence is the urination disorder as the leakage of urine without her own volition and the woman's representative disease which reduces the quality of life. The electromagnetic therapy has high possibility of development because it has no needs of operant exercise, no arousing of shame and impossibility of infection. But, it has improvement points such as uniformity of the treatment protocol, patient dependence and absent of patient monitoring system. With these demands, the system which stimulate the pelvic flaw muscle with electromagnetic and monitoring the patient status during the therapy is proposed, in this study. The developed patient adapted electromagnetic therapy system with monitoring device is regarded as the patient affinitive treating method by reducing the risks, improving the efficiency with patterned protocol and pre/post therapy. These results, in this study, can bring the safe and organized treatment method to incontinence patients and can lead to a variable study on electromagnetic therapy in urine incontinence.
