A Novel Design of Low Power, High Speed SAMM and its FPGA Implementation

matrix multiplication is a computationally intensive problem and a prerequisite in various image processing applications like spatial and frequency filtering, edge detection and convolution. Being a core part of various applications in portable devices like mobile phones, demand for high speed and low power consumption is extremely high. This work demonstrates an effective design and efficient implementation of the Matrix Multiplication using Systolic Architecture and Ancient mathematics. For efficient implementation and maximum speed-up, integer arithmetic was used. Three main steps of the work, i.e. design, simulation and implementation, were accomplished. For design and simulation, Verilog HDL was used. The design was simulated using modelsim10.1d and synthesized using Xilinx Planahead 12.1. The work also includes the comparison between three design approaches of the matrix multiplication using systolic architecture. In the first design approach, array multipliers were used. In the second approach, Wallace tree multipliers were used and in the final approach, matrix multiplier design was based on Ancient multiplication technique.
Design method for gushed light field: aerosol-based aerial and instant display

We present a new method to render aerial images using aerosol-based fog screens. Conventional fog screens are easily affected by air flow, and their fog generators occupy large areas. In this study, we propose to add new tradeoffs between the display time and the payloads. We employ aerosol distribution from off-the-shelf sprays as a fog screen that can resist wind and has high portability. Results showed that the minimum weight of the entire system is approximately 600 g including all components, the screen raise time is approximately 0.5 s, the disappearance time is approximately 0.4 s, and the maximum wind speed at which we can project images is approximately 10 m/s. We conducted user studies on wearable applications, aerial imaging with a drone or radio-controlled model car, multi-viewpoint display, and a display embedded in the environment. This study will contribute to the exploration of new application areas for fog displays, and will augment expressions of entertainment and interactivity.
MemMON: run-time off-chip detection for memory access violation in embedded systems

To deploy a memory protection mechanism, it requires CPU support hardware components like Memory Management Unit (MMU) or Memory Protection Unit (MPU). However, in embedded system, most of microcontrollers lack to be equipped these features because they cause the system incurred hardware cost and performance penalty. In this paper, a method to detect memory corruption at run-time without incurring hardware cost is proposed. Embedded system processor does not require having MMU or MPU. Off-chip detection based on FPGA by hooking on memory bus to monitor memory access for multitasking Realtime Operating System (RTOS) application is explored. Our solution, called MemMON, by combining hardware/software can detect memory access error such as task's stack overflow, task's reading/writing to code/data segments of the other tasks or memory access violation to OS kernel efficiently. In experimental evaluation, a comparison of realtime schedulability is carried out for both using and not using MemMON. Using our MemMON causes realtime schedulability of the system dropped-off about 3 times.
Two-stage Recognition of Raw Acceleration Signals for 3-D Gesture-Understanding Cell Phones

As many functionalities like cameras and MP3 players are converged to cell phones, more intuitive interaction methods are essential beyond tiny keypads. In this paper, we present gesture-based interactions and their two-stage recognition algorithm. Acceleration signals are generated from accelerometer. At the first stage, they are hierarchically modelled and matched as basic component and their relationships by Bayesian networks. At the second stage, they are further classified by SVMs for resolving confusing pairs. Our system showed enough recognition performance for commercialization; with 100 novice users, the average recognition rate was 96.9% on 11 gestures (digits 1-9, O, X). The algorithms have been adopted in the world-first gesture-recognizing Samsung cell phones since 2005.
Neoclassical toroidal viscosity and error-field penetration in tokamaksa)

A model for field error penetration is developed that includes nonresonant as well as the usual resonant field error effects. The nonresonant components cause a neoclassical toroidal viscous torque that tries to keep the plasma rotating at a rate comparable to the ion diamagnetic frequency. The new theory is used to examine resonant error-field penetration threshold scaling in ohmic tokamak plasmas. Compared to previous theoretical results, the plasma is found to be less susceptible to error-field penetration and locking, by a factor that depends on the nonresonant error-field amplitude.
MESH GENERATION AND OPTIMAL TRIANGULATION

We survey the computational geometry relevant to nite element mesh generation. We especially focus on optimal triangulations of geometric domains in two-and three-dimensions. An optimal triangulation is a partition of the domain into triangles or tetrahedra, that is best according to some criterion that measures the size, shape, or number of triangles. We discuss algorithms both for the optimization of triangulations on a xed set of vertices and for the placement of new vertices (Steiner points). We brieey survey the heuristic algorithms used in some practical mesh generators.
Development of a Portable Electronic Nose System for the Detection and Classification of Fruity Odors

In this study, we have developed a prototype of a portable electronic nose (E-Nose) comprising a sensor array of eight commercially available sensors, a data acquisition interface PCB, and a microprocessor. Verification software was developed to verify system functions. Experimental results indicate that the proposed system prototype is able to identify the fragrance of three fruits, namely lemon, banana, and litchi.
Title: Flutamide and biomarkers in women at high risk for ovarian cancer: preclinical and clinical evidence

We hypothesized (1) preclinical biologic evidence exists for the role of androgens in ovarian cancer development and (2) flutamide treatment of women at high risk (HR) for ovarian cancer may identify meaningful tissue biomarkers of androgen action and of ovarian cancer initiation. We showed that androgen ablation of male mice led to a 24-fold decrease in tumor burden from serous ovarian cells. In a phase 2 study, we studied the effect of pre-operative flutamide treatment (125 mg/day x6 weeks) in 12 women vs. 47 controls, 47% with BRCA mutation. We analyzed immunohistochemical scores of candidate proteins CSF-1, CSF-1R, and ErbB4in the epithelium and stroma of fallopian tube, ovary, and ovarian endosalpingiosis (ES). Flutamide decreased the levels, notably, of CSF-1 and ErbB4 in ovarian stroma (P≤ 0.0006) and ES (P≤ 0.01); ErbB4 in ovarian epithelium (P=0.006) and CSF-1R in ES (P=0.009). Our logistic regression model clearly distinguished the flutamide patients from controls (P ≤ 0.0001). Our analysis of the precision of this model of CSF-1 and ErbB4 expression in ovarian stroma achieved 100% sensitivity and 97% specificity (AUC=0.99). Thus, our data suggest that a short 6-week exposure of flutamide reversed elevated levels of CSF-1 and ErbB4 (both of which we had previously found correlated with HR status). CSF-1 and ErbB4 in ovarian stroma led to a model with high predictive value for flutamide sensitivity. The effect of flutamide on marker expression in ES, previously associated with BRCA carrier status, suggests that ES may be a latent precursor to pelvic serous cancers. Introduction Strong evidence has accumulated that suggests an etiologic association between androgens and the development of ovarian cancer (OC). Studies of an epidemiologic, genetic, and biologic nature have formed the basis of the evidence, already largely summarized (1-3). The ovaries and fallopian tubes are androgen-sensitive organs; at menopause, this milieu may help promote transformation of the relevant epithelium.

ADAPTIVE LATERAL INHIBITION FOR NON-NEGATIVE ICA

We consider the problem of decomposing an observed input matrix (or vector sequence) into the product of a mixing matrix with a component matrix , i.e. , where (a) the elements of the mixing matrix and the component matrix are non-negative, and (b) the underlying components are considered to be observations from an independent source. This is therefore a problem of non-negative independent component analysis. Under certain reasonable conditions, it appears to be sufficient simply to ensure that the output matrix has diagonal covariance (in addition to the non-negativity constraints) to find the independent basis. Neither higher-order statistics nor temporal correlations are required. The solution is implemented as a neural network with error-correcting forward/backward weights and linear anti-Hebbian lateral inhibition, and is demonstrated on small artificial data sets including a linear version of the Bars problem.
ec 2 00 5 Notes on Generalised Nullvectors in logarithmic CFT

In these notes we discuss the procedure how to calculate nullvectors in general indecomposable representations which are encountered in logarithmic conformal field theories. In particular, we do not make use of any of the restrictions which have been imposed in logarithmic nullvector calculations up to now, especially the quasi-primarity of all Jordan cell fields. For the quite well-studied cp,1 models we calculate examples of logarithmic nullvectors which have not been accessible to the older methods and recover the known representation structure. Furthermore, we calculate logarithmic nullvectors in the up to now almost unexplored general augmented cp,q models and use these to find bounds on their possible representation structures.
The Usefulness of the Virtual Speaking Head, as Well as 3D Visualization Tools in the New Presentation Technologies

Usefulness of the Slovak-speaking virtual head, as well as 3D visualization tools in the new communication, teaching and presentation technologies, as well as in a variety of audiovisual communications software technologies is almost unlimited. One of the options is the learning through technologies for hearing impaired people. Other, which is a most desired technology, is the use of a virtual head in the field of different communication forms. In the field of crisis management, where the virtual head present the warning messages and navigates during the evacuation of people from reproducing the public institutions such as schools, theatres, etc. 3D visualization tools, as well as Slovak-speaking head and Slovak speech visemas have been designed and tested in our Institute.
Group versus Individual Reward in the Asch Experiment without Confederates

This study examined whether rewarding participants’ principles would affect conformity of the minority responders in the Asch experiment. Twenty groups of four university male students (N = 80; 19 - 24 years old; mean age, 20.7 and SD, 1.32) participated in the Asch conformity experiments without using confederates, as developed by Mori and Arai (2010). Participants were randomly assigned: one of each foursome to the minority condition and the remaining three to the majority condition. In the half of the groups, the participants were told they would be rewarded individually depending on their each performance (Individual Reward condition). The other half were told to be rewarded group-wise (Group Reward condition). The results showed that the minority responders of the Group Reward groups conformed to the majority, while no minority responders conformed to the majority in the Individual Reward groups.
On the Formation and Manipulation of Reference States

Experimental and empirical evidence shows that the utility an individual derives from a certain state depends on the reference state she compares it to. According to economic theory, this reference state is determined by the past, present and future outcomes of either the individual herself or her reference group. The experiment described in this paper suggests that, in addition, reference states depend to a significant degree on non outcome-relevant environmental factors. It shows that reference states - and hence utility - can relatively easily be manipulated without changing people’s outcomes.
Microwave ablation: state-of-the-art review

This paper reviews state-of-the-art microwave ablation (MWA) of tumors. MWA is a novel method for treating inoperable tumors, ie, tumors that cannot be treated surgically. However, patients generally choose removal of the tumor by conventional techniques. A literature review of MWA for breast, liver, lung, and kidney tumors is reported here, with tabulation of our findings according to the type of technique used, with a detailed description of the time, type of microwave generator used, and number of patients treated with MWA. In some cases, the subjects were not human patients, but pig or bovine liver specimens. MWA is a technique that has proved to be promising and likely to be used increasingly in the ablation of cancerous tumors. However, MWA needs to be used more widely to establish itself as a common tool in the treatment of inoperable tumors.
Hyperglycemia accelerated endothelial progenitor cell senescence via the activation of p38 mitogen-activated protein kinase.

BACKGROUND Both the number and function of bone marrow-derived endothelial progenitor cells (EPCs) have been shown to be impaired in patients with diabetes mellitus. Therefore, we investigated the effect of glucose on the senescence of EPCs. METHODS AND RESULTS EPCs were isolated from human peripheral blood and characterized to evaluate the effect of glucose (in 5-12.5 mmol/L) on the rate of senescence by acidic beta-galactosidase staining. The phosphorylation of p38 mitogen-activated protein kinase (MAPK) level was analyzed by ELISA. The exposure of cultured EPC to high glucose (HG; 12.5 mmol/L) significantly accelerated the rate of senescence compared with that in osmolar control (L-glucose) during 10 days culture. An inhibitory effect of HG on EPC proliferation disclosed by an MTS assay. The phosphorylation of p38 MAPK in EPCs was also increased by glucose compared with control in a dose-dependent manner. HG-induced EPC senescence was significantly inhibited by the addition of an inhibitor of the p38 MAPK, SB203580. CONCLUSIONS HG accelerates the onset of EPCs senescence leading to the impairment of proliferative activity, which might be related to the phosphorylation of p38 MAPK.
An innovative perturb, observe and check algorithm for partially shaded PV systems

The performance of every photovoltaic (PV) module constituting a PV system can be slightly or strongly different from each other. This factual functioning of PV systems results in some new effects to bear in mind, including the appearance of new peak power points on the output P-V characteristic. However, traditional Maximum Power Point Tracking (MPPT) control methods do not manage these phenomena and can get lost easily. Even though many papers have been reported recently in relation to new MPPT control techniques, none of these solves satisfactorily the problem of local Maximum Power Points (MPPs). In fact, despite their complexity, the operating point is likely to converge on a local MPP under certain conditions reducing significantly the global efficiency of the PV system. In order to overcome this drawback, a new MPPT is proposed consisting of a traditional Perturb & Observe (PO) algorithm but improved with a second stage able to detect these anomalies on the PV generator curve. With this aim, the casuistry of the problem of local MPPs has been analyzed in depth. From the obtained conclusions a new checking stage has been developed and tested. The experimental results carried out have shown not only the capability to find the real MPP under any circumstance but also the facility to get it in a fast and reliable way.
Teaching software project management using simulations

An experience-dominated subject like software project management cannot be learned by merely attending lectures. Additional labs, however, even with only modest real-life projects, call for substantial effort to be spent by the instructors as well as by the partaking students. Our experience shows that using a software development simulation tool enhances the mix of methods used in conventional teaching substantially.
Determination of left ventricular end-systolic pressure-volume relationships by the conductance (volume) catheter technique.

Using a multielectrode conductance catheter to estimate continuous left ventricular volume we determined the end-systolic pressure-volume relationship (ESPVR) in situ in open-chest anesthetized dogs. Dogs (n = 8) were studied in the control state and after pharmacologic sympathectomy (hexamethonium) and surgical vagotomy both before and after the administration of dobutamine. ESPVR was measured during brief (5 to 6 sec) preload reduction by balloon occlusion of the inferior vena cava (IVCBO). The relationship was highly reproducible. The slope (Ecs) and volume intercept (Vo) (mean +/- SD) in the control series were 5.8 +/- 3.6 mm Hg/ml and 6.5 +/- 12.5 ml, respectively. Upon release of the IVCBO (preload recovery), Ecs was 7.7 +/- 3.6 mm Hg/ml and Vo was 12.4 +/- 9.6 ml (p less than .01). Autonomic blockade produced a 50% reduction in Ecs and a concomitant decrease in Vo (p less than .01), and eliminated the difference between ESPVR generated by preload reduction (IVCBO) and preload recovery (IVCBO release). Subsequent dobutamine infusion increased Ecs to 6.1 +/- 3.5 mm Hg/ml and Vo to 4.1 +/- 6.9 ml, consistent with reported changes of the ESPVR with positive inotropic intervention. A small artifact of right ventricular filling was observed in the left ventricular volume catheter signal, but this did not appreciably alter the ESPVR. These results demonstrate the feasibility of the determination of ESPVR in situ by the conductance catheter and brief IVCBO and underline the importance of the use of rapid load changes to minimize reflex activation during the measurements.
Robust real time material classification algorithm using soft three axis tactile sensor: Evaluation of the algorithm

Materials and textures identification is a desired ability for robots. Developing such systems require tactile sensors that have enough sensitivity and spatial resolution, and the computational intelligence to meaningfully interpret sensor data. This paper introduces a texture classification algorithm utilizing support vector machine (SVM) classifier. Data taken from a novel three axis tactile sensor that utilize magnetic flux measurements for transduction was used to obtain the three dimensional tactile data. Frobenius norm calculated from the covariance matrix of the above data and the mean values of the three dimensional sensor data were used as features. Palpation velocity and small vertical load variances had minimum influence on the proposed algorithm. We have compared this algorithm with two other classification methods. They are: classify using the feature spatial period that is calculated from principal frequencies of the textures/material, and classify using neural network classifier with special properties of each material's tactile signals as features. For eight classes of material, the proposed algorithm performed faster and more accurately than the comparators when the scanning velocity and the vertical load varied.
A real-time pulse wave detection device basing on signal envelope

We design a portable ECG (electrocardiograph) and PPG (photoplethysmograph pulse wave) measurement device which can simultaneously detect ECG and PPG signal, analyze arrhythmia and calculate SpO2 (oxygen saturation of blood). It consists of two parts: the main and the sub. MSP430 MCU is the most important part. Besides, there are front-end amplifiers, filter circuit, Bluetooth module, data management module, keyboard and LCD display module, etc. The device can detect QRS complex and PPG signals in real time. For the Fantasia database and patients, the monitor can correctly judge the QRS complex of ECG signals and pulse wave signal.
Cuff-less and Noninvasive Measurements of Arterial Blood Pressure by Pulse Transit Time

The current blood pressure (BP) measurement devices are mostly built on the principle of auscultation, oscillometry or tonometry, all of which use an inflatable cuff to occlude or unload the artery. The need of a cuff in these devices limits the further reduction in size and power consumption, and restricts the frequency and ease of their usage. Therefore, this study aims to develop a cuff-less and noninvasive technique for measuring BP by pulse transit time. The technique was evaluated on 85 subjects, aged 57plusmn29 yrs. , including 36 males and 39 hypertensives, over an average period of 6.4 wks. A total of 999 pairs of systolic BP (SBP) and diastolic BP (DBP) estimations were made. The average of BP readings reported by an experienced registered nurse and those obtained from a clinically approved automatic BP meter was used as reference. It is found that the estimated SBP and DBP differed from the reference BP by 0.6plusmn9. 8 mmHg and 0.9plusmn5. 6 mmHg respectively. When compared to the AAMI requirement (5plusmn8 mmHg for both SBP and DBP estimation), the results suggest that the cuff-less technology has great potential to be developed into wearable devices that are useful in self BP monitoring for home healthcare and eventually in clinical diagnosis
A survey of bitmap index compression algorithms for Big Data

With the growing popularity of Internet applications and the widespread use of mobile Internet, Internet traffic has maintained rapid growth over the past two decades. Internet Traffic Archival Systems (ITAS) for packets or flow records have become more and more widely used in network monitoring, network troubleshooting, and user behavior and experience analysis. Among the three key technologies in ITAS, we focus on bitmap index compression algorithm and give a detailed survey in this paper. The current state-of-the-art bitmap index encoding schemes include: BBC, WAH, PLWAH, EWAH, PWAH, CONCISE, COMPAX, VLC, DF-WAH, and VAL-WAH. Based on differences in segmentation, chunking, merge compress, and Near Identical (NI) features, we provide a thorough categorization of the state-of-the-art bitmap index compression algorithms. We also propose some new bitmap index encoding algorithms, such as SECOMPAX, ICX, MASC, and PLWAH+, and present the state diagrams for their encoding algorithms. We then evaluate their CPU and GPU implementations with a real Internet trace from CAIDA. Finally, we summarize and discuss the future direction of bitmap index compression algorithms. Beyond the application in network security and network forensic, bitmap index compression with faster bitwise-logical operations and reduced search space is widely used in analysis in genome data, geographical information system, graph databases, image retrieval, Internet of things, etc. It is expected that bitmap index compression will thrive and be prosperous again in Big Data era since 1980s.
