Architecture Approach for Mobile Service Security

Mobile computing is a relatively new field. While the challenges arising from mobility and the limitations of the portable devices are relatively well understood, there is no consensus yet as to what should be done to address these challenges. A comprehensive solution has to address many different aspects, such as the issue of dynamically changing bandwidth, the power, computational, and other limitations of the portable devices, or the varying availability of services in different environments. A Mobile service is programmable application logic accessible using standard Internet protocols. In this paper, we present our architecture for such adaptive mobile service security applications. We motivated the architecture by classifying likely mobile applications and identified common properties. The architecture intends to be more general than previous work with respect to adaptability, flexibility, and user mobility. We developed various pieces of the overall architecture and collected some preliminary experience with adaptive mobile applications. We give an overview of the intersection of the areas of software architecture and mobile applications. We consider the mobile applications, which represent the computing functionality designed to migrate across hardware devices at runtime and execute on mobile hardware platforms, and the mobile systems, which are computing applications that include mobile software and hardware elements.
Frequency reconfigurable lte antenna with u shaped open end for portable wireless devices

In this paper, a frequency tuning method for an U-shaped slot antenna for long term evaluation (LTE) wireless communication devices is presented and the performance of the antenna (return loss, total and radiation efficiencies…etc) is reported. The lower operating frequency of the antenna (700 - 960 MHz) is switched with different inductor loadings from 110 nH to 30 nH. The inductor component loads the U-slot antenna and thus enables to tune the frequency of low band (700 - 960 MHz). Higher bands (1710 - 2700 MHz) of the antenna remain unchanged with different inductor loadings. The impact of the inductor position is also investigated and the results are reported. The antenna presented in the paper is comparable with that of Cho-Kang Hsu’s publication. However, in Chos publication, only one low band is covered. In our design, all of existing commercial LTE frequency bands (Band 17 - Band 7) used in typical mobile devices are covered by the proposed antenna.
Traffic density estimation, vehicle classification and stopped vehicle detection for traffic surveillance system using predefined traffic videos

change due to weather or sun-light reflections decreases its effectiveness. It is also computationally inefficient [2]. The third method, background subtraction, is the mostly seen method in the literature for effective motion tracking and moving object identification [2, 4, 6, 9, 10, 11]. In background subtraction, background can be static, in which a fixed background is obtained beforehand and used in the entire process; or dynamic, in which background is dynamically updated with changing external effects like weather. Static background may not be effective in most applications, many methods include dynamic background subtraction. In [19], the background is detected dynamically by using dynamic threshold selection method. In [22], land mark based method and BS&Edge method are used to remove the shadow from the scene. Different classification techniques have been employed after the moving objects are detected in order to identify the
Reduce Energy Consumption and Increase the Lifetime of Heterogeneous Wireless Sensor Networks: Evolutionary Approach

Heterogeneous wireless sensor networks consist of sensor nodes with different capability, such as different computing power, amount of energy and sensing range. One of the most important issues in heterogeneous wireless sensor network is the energy consumption that has the important effect on the lifetime of the network. In this paper the evolutionary approach to decrease the energy consumption and increase the lifetime of the heterogeneous wireless sensor network is introduced. The main achievement of this method is to reduce the execution times of algorithm. Keywords: Wireless sensor network, energy consumption, lifetime, genetic algorithm

This system provides storing information electronically and provides an efficient way of faster communication between the doctor and patient. The patient can check their health readings from anywhere, anytime. The patient can also use Home-care service where the patient has to answer certain questions based on their symptoms.
A Network Coding based DTN Convergence Layer Reliable Transport Mechanism over InterPlaNetary Networks

The realization of deep space scientific missions are enabled by the developments in the space technologies. TCP can not provide effective communication service in deep space links because of the long propagation delay and high BERs characteristics.Scientific community propose Delay Tolerant Network (DTN) for resolving the communication problem between earth and other planet. DTN introduces a new layer in the protocol stack called Bundle Layer that is placed between application layer and transport layer.DTN calls the transport protocols that it uses to move data across different networks convergence layers. This study present a novel Network Coding based convergence layer Reliable TransPort mechanism(NC-RTP) in order to provide effective communication service between DTN peers. This mechanism transmit a coded bundle every M original bundles(M is related to the packet error rate of the communication link). The coded bundle is a random linear combination of previous M original bundles. Using coded bundle and (M-1)original bundles, the receiver could decode and generate a single lost bundle of previous M original bundles . In this way, NC-RTP could compensate any single lost bundle in (M+1) transmitted bundles(including M original bundles and 1 coded bundle). Our theoretical and simulation performance evaluation results reveal that NC-RTP can enhance transmit reliability and make file transfered faster.
Cognitive Skill and Web-Based Educational Systems

Can Web-based educational systems (WBES) really facilitate cognitive skill development? It would appear from the common rhetoric that learning occurs as a somewhat automatic process through interactive multimedia. Moreover, it is taken for granted that a collaborative approach to life-long learning and knowledge transfer is a guaranteed WBES outcome. An examination of current multimedia courseware reveals the opposite is true. This is where effective learning management systems (LMS) can make all the difference. To this end there have been a number of developments towards identifying the management of collaborative instructional environments (Bhattacharya 2000). However, if we want to sustain the momentum towards achieving positive outcomes from interactive multimedia in a shared knowledge/experiential learning network (Sims 2000), we must first understand more about how to manage an individual's capacity to access information through human-computer interaction (HCI) (Preece 1994). Once we understand more about the HCI phenomenon and learn how to manage the so called e- Learning environment successfully, we may be in a position to claim that interactive-context-mediated learning has arrived (von Wodtke 1993). This paper discusses how the perspective of instructional design, where first principles take a fine grained approach to identify how the learning/instructional context is affected by multimedia. To assist with this, a Meta-Knowledge Processing Model is proposed as a courseware designing tool which identifies the major variables involved in an interactive multimedia learning environment. Because multimodal instructional materials tap into an individual's spatial ability, several controversial issues, relating to cognitive skill acquisition within a WBES, will be exposed. The paper commences by defining some of the problems facing courseware designers; providing a revision of instructional design terminology as a strategic methodology for understanding the complexity involved in bringing the best from the traditional pedagogy into the technological arena. It then discusses some of the operational principles of WBES environments. This is followed by an outline of expected or measurable outcomes. Conditions and limitations are outlined before the final section which addresses the realization that technological solutions will not always be the critical method to achieve desirable instructional outcomes. In closing, this paper will show how current progress points towards the future, revealing that much more work is needed to unlock the mysteries that surround multimodal instructional strategy development.
Prevalence of Microalbuminuria in Hypertensive Patients

A total of 657 uncontrolled hypertensive patients (BP > 140/90 mm Hg in non-diabetics and BP >130/85 mm Hg in diabetic patients) were studied and followed for 12 months. Out of which 374 (56.93%) were male and 283 (43.07%) were female. Retinopathy was observed in 91 (13.85%) cases and Left ventricular hypertrophy was seen in 91 (13.85%) patients. Out of 374 male patients 198 (52.94%) were smokers while 176 (47.06%) were non-smokers. Hypertension is an established risk factor for cardiovascular as well as renal disease. Prevalence of microalbuminuria in hypertensive patients suggests that screening for microalbuminuria is essential for intervention and prevention of further complications like end stage renal disease and cardiovascular disease. It is much more essential to screen for early nephropathy by testing microalbuminuria in hypertensive patients prevent or halt the earliest stages of damage by vigorous control of hypertension. Further studies in large scale population are required to further verification of microalbuminuria as a screening tool to prevent progression of cardiovascular and renal disease.
WOULD MANDATORY TEACHING OF BLS, ACLS AND PALS IMPROVE THE KNOWLEDGE, ATTITUDE AND PRACTICE OF MEDICAL STUDENTS IN EMERGENCY CARE?

Background and objective: The medical students should be trained in BLS/ACLS/PALS in order to attain the skills for emergency patient management. The objective of the study is to compare the knowledge, attitude and practice about BLS/ACLS/PALS among the interventional and non-interventional groups both before intervention and after intervention. Methods: This interventional study was done among final year medical students and house surgeons in six Medical colleges of Northern Kerala.The study subjects were categorized into two groups,Category 1 received an orientation class on BLS/ACLS/PALS and students belonging to category 2 did not receive the orientation class. A pre-validated pretested questionnaire to assess the Knowledge, Attitude and Practice of medical students regarding BLS/ACLS/PALS was distributed after the orientation class.The control group (category 2) who did not receive the orientation class also were given the questionnaire same as that of other group. Results: Total of 608 students participated in this study.Out of which 325 received an orientation class. Unpaired t-test done in pretest among interventional and non-interventional group showed p value>0.01 which implied that both groups were comparable. The mean scores of Knowledge, attitude and practice in the post test increased to 8.111±1.507, 2.328±. 743, 2.065±. 297 among house surgeons and an increment to 6.260±1.087, 2.277±. 474, 1.659±. 659 among final years in the interventional group as when compared with the scores of the non-interventional group. Paired t test also showed significant difference among interventional group while there was no change in the non-interventional group. (p>0.05). Conclusion: BLS/ACLS/PALS training among undergraduates can improve the Knowledge, Attitude and Practice of medical students thereby increasing the resuscitation as well as the survival of patients in emergency care.

An Accurate Calorimetric Loss Measurement Method for SiC MOSFETs

An accurate measurement of conduction and switching losses in the power semiconductor devices is necessary in order to design and evaluate the thermal management system of modern converter systems. Conventionally, electrical measurement methods, such as the double-pulse tests (DPTs), are used for measuring the switching losses. However, with the advent of wide-bandgap (WBG) devices that have fast switching transients, it is rather difficult to capture the waveforms accurately during switching transitions, and consequently, the measurement of switching loss becomes inaccurate. In addition, the measurement of switching waveforms depends on the voltage and current probes, as well as the oscilloscope used for the measurement, which makes this method prone to errors. This necessitates the use of measurement methods, which can provide much higher accuracy than the existing conventional electrical methods. Calorimetric methods are based on comparatively slow temperature measurements and do not rely on the measurements of fast switching transitions of voltages and currents, thus eliminating the demand for measuring fast switching transitions. This paper presents an accurate calorimetric method for measuring the device losses, which can be used to determine individual loss components accurately (conduction, turn-on, and turn-off losses). In addition to the turn-on and turn-off losses, this method can evaluate the charging and discharging losses of the device. The novelty of the method lies in the fact that a single setup can be used to measure all possible losses that can occur in a device during converter operation. The calorimetric test setup is described, and a novel modulation scheme is introduced, which enables the segregation of the individual losses. The experimental test setup is built and the method is verified by measuring the losses of a 900-V, 23-A Wolfspeed C3M0120090D SiC MOSFET.
A Drosophila Insulator Interacting Protein Suppresses Enhancer-Blocking Function and Modulates Replication Timing

Insulators play important roles in genome structure and function in Drosophila and mammals. More than six different insulator proteins are required in Drosophila for normal genome function, whereas CTCF is the only identified protein contributing to insulator function in mammals. Interactions between a DNA binding insulator protein and its interacting partner proteins define the properties of each insulator site. The different roles of insulator protein partners in the Drosophila genome and how they confer functional specificity remain poorly understood. Functional analysis of insulator partner proteins in Drosophila is necessary to understand how genomes are compartmentalized and the roles that different insulators play in genome function. In Drosophila, the Suppressor of Hairy wing [Su(Hw)] insulator is targeted to the nuclear lamina, preferentially localizes at euchromatin/heterochromatin boundaries, and is associated with the Gypsy retrotransposon. The properties that the insulator confers to these sites rely on the ability of the Su(Hw) protein to bind the DNA at specific sites and interact with Mod(mdg4)-67.2 and CP190 partner proteins. HP1 and insulator partner protein 1 (HIPP1) is a recently identified partner of Su(Hw), but how HIPP1 contributes to the function of Su(Hw) insulators has not yet been elucidated. Here, we find that mutations in the HIPP1 crotonase-like domain have no impact on the function of Su(Hw) enhancer-blocking activity but do exhibit an impaired ability to repair double-strand breaks. Additionally, we find that the overexpression of each HIPP1 and Su(Hw) causes defects in cell proliferation by limiting the progression of DNA replication. We also find that HIPP1 overexpression suppresses the Su(Hw) insulator enhancer-blocking function.
The prognostic value of systemic immune-inflammation index (SII) in patients after radical operation for carcinoma of stomach in gastric cancer.

Background The inflammatory reaction, which plays a key role in tumor microenvironment, is associated with the tumor development, progression and metastasis. We aim to estimate the potential prognostic value of systemic immune-inflammation index (SII) in patients after radical operation for carcinoma of stomach in gastric cancer. Methods One hundred and eighty-two patients with gastric cancer who underwent radical operation for carcinoma of stomach from January 2009 to December 2012 were enrolled and divided into a low SII group (<600×109 cells/L) and a high SII group (SII ≥600×109 cells/L) based on the optimal cutoff value of SII. The clinicopathological features were analyzed and compared between the two groups of patients. We analyzed the disease-free survival (DFS) and the overall survival (OS) by Kaplan Meier survival curve and log-rank test. The prognostic factors were used to evaluate by univariate analysis, and the independent prognostic factors were assessed by using multivariate Cox proportional hazards regression model. Results The median DFS and OS of all patients were 18.67 and 22.83 months, respectively. According to the univariate and multivariate analysis, the optimal cutoff value of SII had prognostic significance on DFS and OS. The median DFS and OS in low SII group were longer than those in high SII group (21.43 vs. 17.57 months, 28.03 vs. 18.30 months, respectively). The radical resection, type of surgery, metastatic lymph nodes ratio (MLNR), lymphocyte, SII, carcinoembryonic antigen (CEA) and Borrmann classification were the independent prognostic factors in gastric carcinoma. At the same time, the patients with MLNR in low SII group had longer DFS and OS than those with MLNR in high SII group, especially in patients with high MLNR. Conclusions SII may serve as a convenient, low-cost and noninvasive prognostic marker for patients after radical operation for carcinoma of stomach in gastric cancer.
The Class Practice for Advancing from CS Unplugged to Full-Fledged Programming

The course we teach has about 40 students per class, aged 16 through 17 years. Since the students’ major field of study is Management Information, they need to learn programming techniques. However, the results of the survey described below show that not a few students consider themselves to have insufficient understanding of programming or think that they are not good at programming. We are examining ways to improve this situation. CS Unplugged is a method of teaching information science without using computers, first proposed by Tim Bell of the University of Canterbury in New Zealand. While CS Unplugged is said to be effective in teaching information science. To address this topic, we implemented CS Unplugged for a group of students, and looked at their responses. Accordingly, we propose a new method of advancing from CS Unplugged to full-fledged programming. The proposed method begins with conducting a CS Unplugged activity, and then continues on to writing a program on the same theme and further to its abstraction in Java. Accordingly, we propose advancing from CS Unplugged to full-fledged programming through a new Four-Step Method. -----------------------------------------------------------------------* Corresponding author. International Journal of Sciences: Basic and Applied Research (IJSBAR) (2015) Volume 24, No 5, pp 43-50 44 The proposed method consists of the following steps: Step 1, A CS Unplugged activity; Step 2, A CS Plugged activity; Step 3, Preparing pseudocode; and Step 4, Writing Java source code.
Multi-Sensory Virtual Environments for Investigating the Past

A human depends on all five senses: visuals, audio, smell, taste and touch to perceive an environment. It is not only the individual senses, but also their interaction that plays a key role in enabling us to understand the world around us. Virtual archaeology is being increasingly used to investigate the past. Failure to consider all senses in these reconstructions runs the very real danger of misrepresenting ancient environments and how they may have been perceived by our ancestors. This paper describes Real Virtuality: true high-fidelity multi-sensory virtual environments, and shows how such an approach may give historians a more valid means of considering the past.
307-LB: IL1R1 Mediates Celastrol’s Leptin-Sensitization and Antiobesity Effects

Celastrol, isolated from the root extracts of thunder god vine, is the most potent anti-obesity agent that has been reported to date. Celastrol increases leptin sensitivity in the hyperleptinemic diet-induced obese (DIO) mice and leads to 45-50% weight loss in this model, with either no or only marginal effects in db/db, ob/ob or lean mice. In this work, we first showed that lipocalin 2 (LCN2) is the most upregulated gene in the hypothalamus of DIO mice after celastrol treatment. Celastrol treatment leads to a significant upregulation of LCN2 both in bone marrow, plasma, and the hypothalamus. However, LCN2 does not play a significant role in suppressing appetite and reducing body weight or mediating celastrol’s antiobesity effects. Secondly, by using systems biology approaches for analysis of temporal regulations of the hypothalamic transcriptome of DIO, lean and db/db mice that were treated with celastrol, we have identified interleukin 1 receptor 1 (IL1R1) as a mediator of celastrol action and documented that IL1R1-deficient mice is completely resistant to celastrol’s leptin sensitization, anti-obesity, antidiabetic and anti-NASH effects. Thus, IL1R1 is a gate-keeper for celastrol’s metabolic actions. Disclosure X. Feng: None. Funding Fidelity Biosciences Research Initiative
