Distributed-Memory-Based FFT Architecture and FPGA Implementations

A new class of fast Fourier transform (FFT) architecture, based on the use of distributed memories, is proposed for field-programmable gate arrays (FPGAs). Prominent features are high clock speeds, programmability, reduced look-up-table (LUT) and register usage, simplicity of design, and a capability to do both power-of-two and non-power-of-two FFTs. Higher clock speeds are a consequence of new algorithms and a more fine-grained structure compared to traditional pipelined FFTs, so clock speeds are typically >500 MHz in 65 nm FPGA technology. The programmability derives from the memory-based architecture, which is also scalable. Reduced LUT and register usage arises from a unique methodology to control word growth during computation that achieves high dynamic range, along with inherent systolic circuit characteristics: simple, regular, uniform arrays of processing elements, connected in nearest-neighbor fashion to minimize wiring lengths. The circuit goal was to maximize throughput and minimize the use of the FPGA LUT and register logic fabric. Comparison results from seven different designs, covering a spectrum of functionality (fixed-size, variable, floating-point and variable non-power-of-two FFTs), different FPGA vendors (Intel and Xilinx) and different FPGA types, showed increases in throughput per logic cell up to 181% with an average improvement of 94%.
The importance of epigenetics in embryonic development and reproductive biotechnology.

It is well established that epigenetics and chromatin modifications are primary factors that can govern gene activity and nuclear architecture. They are also proven to be essential for normal embryonic development and cell differentiation. One important step during mouse development is the establishment of epigenetic reprogramming which is believed to be vital for normal growth and development, however; the mechanism is still poorly understood. Creating embryo using reproductive biotechnology such as IVM/IVF, ICSI and nuclear transfer may cause abnormal epigenetic pattern. This review summarise the role and the importance of epigenetic in embryonic development as well as reproductive biotechnology from research literature mainly in mouse used as a model for mammalian development.
A Top-Down Approach to Building Battery-Less Self-Powered Systems for the Internet-of-Things

This paper presents a top-down methodology for designing battery-less systems for the Internet-of-Things (IoT). We start by extracting features from a target IoT application and the environment in which it will be deployed. We then present strategies to translate these features into design choices that optimize the system and improve its reliability. We look into how to use these features to build the digital sub-system by determining the blocks to implement, the digital architecture, the clock rate of the system, the memory capacity, and the low power states. We also review how these features impact the choice of energy harvesting power management units.
Adult Protection of People with Intellectual Disabilities: Incidence, Nature and Responses.

Background There has been increasing recognition of the importance and extent of abuse of vulnerable adults, including people with intellectual disabilities, leading to the development of monitoring systems. This paper reports findings from one of the largest databases in the UK collected between 1998 and 2005. Method Analysis of the 1926 referrals relating to people with intellectual disabilities included description of the nature of abuse and the responses to the referrals, comparisons to those relating to other client groups and comparisons between those placed locally and those placed out-of-area. Results About one-third of all adult protection referrals related to people with intellectual disability, remaining consistent over time. However, the number of referrals increased significantly. The majority of people lived in residential care or supported living and this was reflected in the nature of the referrals – people were more likely to have been abused in the care home and by staff or service users than those without an intellectual disability. The most common type of abuse was physical abuse. Sexual abuse was more prevalent in the intellectual disability sample than in other client groups. People with intellectual disability were more likely to have experienced follow-up action, usually through more monitoring. There was a different pattern of abuse seen in those placed out-of-area. Conclusions The overall pattern of abuse is similar to that reported in earlier studies. There is some indication that residential situation and in particular being placed in a residential placement out-of-area, may be an important factor in predicting adult protection referrals.
FabNavi : Support system to assemble physical objects using visual instructions

In this FAB age, people can easily duplicate physical parts through personal & social FAB technologies. However, assembling these parts is still troublesome especially when creating complicated items. To solve this problem, we propose a new system, FabNavi, which helps people to assemble physical objects in remote places using visual instructions. FabNavi mainly consists of a pair of a camera and a projector set above the tabletop. People can easily record the assembly processes by pictures and share these instructions on the web. Then other people can re‐ assemble them just by following the visual instructions projected on the remote tabletop. The goal of FabNavi is to create a framework for recording and sharing new universal instructions through the FabLab network. We had many workshops and exhibitions using FabNavi to explore its possibilities and limitations in Tokyo, London, and Taipei. In this paper, we report the concept, implementation, experiences and findings in the workshops.
UNIVERSIDADE TECNOLÓGICA FEDERAL DO PARANÁ PROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA ELÉTRICA E INFORMÁTICA INDUSTRIAL JEAN PAULO NAKATU LONGO ELECTRICAL IMPEDANCE MEASUREMENTS OF CLATHRATE HYDRATES

LONGO, J. P. N. Electrical Impedance Measurements of Clathrate Hydrates. 2015. 84 p. Master Thesis (Graduate Program in Electrical and Computer Engineering of Federal University of Technology – Paraná.). Curitiba, 2015. Among the challenges in the oil and gas industry for hydrocarbon production, a featured area in recent years is known as flow assurance, which involves to guarantee the continuously stream of fluids (oil or gas) through pipelines connecting wellhead to separation systems at topside. One of the main problems is related to the deposition of gas hydrates in pipelines, since these deposits may reduce the effective pipe diameter or even clog pipelines, causing considerable financial losses mainly due to production stop. Gas hydrates or clathrates are crystalline solid ice-like structures, typically formed by water and gas molecules under certain conditions of pressure and temperature. Currently there is no established measurement technique for monitoring the hydrate formation in pipelines. One candidate technique is impedance (or impedance spectrum) measurement of fluids, since it is simple, robust and low cost. With the objective of investigating hydrate formation in a controlled environment, several experiments with three different measuring systems operating three different measuring cells have been performed and evaluated. A fully commercial, a mixed, and a dedicated measuring system were applied for obtaining impedance data of hydrates formation. The experimental tests were performed with a model substance (tetrahydrofuran THF) in mixture with water which allows the monitoring of hydrates formation at ambient pressures (i.e. no need to use a pressurized cell). The first two systems (commercial and mixed) are able to measure the impedance spectrum in the range 10 Hz to 10 MHz. The dedicated system operates at a fixed frequency (typically 5 MHz). The results show that considerable differences in impedance values are observed for the THF-water mixture in liquid conditions and with the presence of hydrates, hence being promising in hydrates formation monitoring. In this way, the developed measurement system allied to appropriated data processing routines has the potential to be applied as simple tool to monitor hydrate formation in pipes.
SURFACE GEOMETRY OF PROTOPLANETARY DISKS INFERRED FROM NEAR-INFRARED IMAGING POLARIMETRY

We present a new method of analysis for determining the surface geometry of five protoplanetary disks observed with near-infrared imaging polarimetry using Subaru-HiCIAO. Using as inputs the observed distribution of polarized intensity (PI), disk inclination, assumed properties for dust scattering, and other reasonable approximations, we calculate a differential equation to derive the surface geometry. This equation is numerically integrated along the distance from the star at a given position angle. We show that, using these approximations, the local maxima in the PI distribution of spiral arms (SAO 206462, MWC 758) and rings (2MASS J16042165–2130284, PDS 70) are associated with local concave-up structures on the disk surface. We also show that the observed presence of an inner gap in scattered light still allows the possibility of a disk surface that is parallel to the light path from the star, or a disk that is shadowed by structures in the inner radii. Our analysis for rings does not show the presence of a vertical inner wall as often assumed in studies of disks with an inner gap. Finally, we summarize the implications of spiral and ring structures as potential signatures of ongoing planet formation.
Bacillus Cereus Bacterium: A Human Pathogen

Species of genus Bacillus are rods capsules of producing endospores and they develop aerobically [1,2] although a few are facultative in the majority of cases in nutrient agar as well as are catalase positive [3]. Bacteria belonging to genus Bacillus are endospore-forming bacteria Gram-positive and aerobic that are distinguished by the rod-designed cell morphology and also catalase generation [4]. Moreover, they are found in varied environments like for example the soil, dust, vegetation, food and gastro-intestinal tracts of different animals and insects [5]. This aptitude to stay alive and develop in such diverse ecosystems is established on the make of their strong endospores [6], their multiplicity in physiological attributes and their growth conditions.
Influences of the encoding instructions on retrieval processes in recall and recognition memory

The purpose of this study was to explore the influences of the encoding instructions on retrieval processes in recall and recognition memory. A set of materials used consisted of low intralist similarity items in Experiment 1 (60 undergraduates), and high intralist similarity items in Experiment 2 (60 undergraduates). In both experiments, one of three retrieval tests was given to the subjects: recall, recognition, or cued recall test. Four types of encoding instruction were crossed with three types of retrieval test. The results showed that subjects performed at the greatest level when the encoding instruction and the retrieval test were compatible, and that cued recall performance was similar to recognition performance regardless of intralist similarity. It was suggested that the results were explained better in relation to the episodic theory and retrieval attributes in recall and recognition—ratherlthan the two-stage theory of recall.
Tax Me, But Spend Wisely : The Political Economy of Taxes, Theory and Evidence from Brazilian Local Governments

This paper shows that local governments are more accountable when they have more capacity to tax their citizens. I construct a principal-agent model of public finance in which public revenues come from taxes and inter-governmental transfers. An increase in taxes keeping transfers constant changes the equilibrium allocation of public revenues towards more public goods and less political rents because citizens have better information on taxes than on transfers. I then consider a program in Brazil that invests in the modernization of local tax administrations. Using 10 years of panel data and quasi-exogenous variations in the timing of program uptake I find that the program increases tax collection of local governments by 11% after four years. This increase in taxes is used to raise local public good provision but not corruption : the share of resources diverted by local politicians in total public revenues decreases as taxes increase. A discontinuity in the rule allocating federal transfers to local governments is used to compare the impact on spending outcomes of an exogenous increase in transfers to that of a raise in tax revenues thanks to the program. Results show, in line with the model’s predictions, that local officials use extra tax revenues more to increase the supply of municipal public goods and less on private rents than they do with extra transfer revenues.

Autonomic Closed Control Loops for Management, an idea whose time has come?

Taking an autonomic approach to management and using closed control loops has been the subject of much research in the Network management community since the early 2000s. It is fair to say that Network Management system developers and users have not adopted Autonomic Management approaches very widely. Most network management systems continue to use an ITU TMN inspired layered approach to management.In recent years, a trend towards implementing autonomic management and closed control loops on management systems built using a TMN architecture has emerged in practice. This trend is requirement driven; an autonomic approach is taken when there is no other option for implementing a feature. It is clear to see a closed control loop approach being taken to implement C-SON (Centralized Self Organizing Networks) features in 4G network management systems in the early 2010s. Autonomic approaches are even more apparent in systems such as ONAP that implement SDN and NFV orchestration. However, the implementation of closed control loops is often pragmatic and rigid, focused on the feature being delivered. Providing systemized support for control loops is in its infancy and has much to learn from the extensive autonomic management literatureThis paper surveys the current state of autonomic management in practice and outlines some research challenges that must be addressed to allow it to be systematically supported in current management systems, with a particular focus on ONAP.
die Beurteilung von Schienenverkehrslärm in der Nacht

schritten wird (LpAmax,6), als Erklärungsgrößen (Prädiktoren), eine bessere Modellgüte aufweisen, als ein Modell nur mit dem Dauerschallpegel als Prädiktor [4] [5]. Die Bedeutung des Maximalpegels zur Beurteilung der Wirkung nächtlichen Verkehrslärms zeigt sich auch in Bezug auf Erkrankungsrisiken: So konnte in der NORAH-Fallkontrollstudie zu Erkrankungsrisiken festgestellt werden, dass beim Fluglärm bereits statistisch signifikante erhöhte Risiken hypertensiver (blutdruckbedingter) Herzerkrankungen und Herzinsuffizienz bei relativ niedrigem 24-Stunden-Dauerschallpegel (LpAeq,24h < 40 dB) auftreten, wenn ein nächtlicher Maximalpegel von 50 dB bei mindestens sechs Flugbewegungen überschritten wurde [6]. Um zu prüfen, ob aus den Erkenntnissen der Lärmwirkungsforschung zur Bedeutung eines Maximalpegelkriteriums bei der Beurteilung des nächtlichen Schienenverkehrslärms Vorschläge zur etwaigen Ergänzung bzw. Änderung der bestehenden Beurteilungsregelungen abgeleitet werden können und welche Auswirkungen Umsetzungsvorschläge haben, wurde vom Hessischen Umweltministerium das interdisziplinäre Gutachten zur „Berücksichtigung eines Maximalpegelkriteriums bei der Beurteilung von Schienenverkehrslärm in der Nacht“ in Auftrag gegeben. Der vorliegende Beitrag fasst die wesentlichen Analysen und Ergebnisse dieses Gutachtens [7] zusammen. Dabei wird zunächst die Schlafqualität definiert, dann anhand einer Analyse der Forschungsliteratur Wirkungskriterien des Lärms auf den nächtlichen Schlaf dargestellt und geeignete akustische Kenngrößen beschrieben. Es werden Ergebnisse von Expositions-Wirkungsanalysen mit verschiedenen Wirkungsund AkustikKenngrößen und hieraus abgeleitete Vorschläge von Zumutbarkeitsgrenzen vorgestellt, deren Auswirkungen anhand von Fallbeispielen aufgezeigt werden.
Bluff Body Noise and Flow Control with Atmospheric Plasma Actuators

Plasma actuators operating in atmospheric air were employed to modify aerodynamic flow over a bluff body. The model consisted of a cylinder and a torque link that was installed on the lee side of the cylinder. The objective was to reduce the broadband noise that is mainly generated by the impingement of the cylinder wake on the torque link. The plasma actuators were configured to produce dielectric barrier discharges, through which the flow separation from the cylinder was enhanced by the externally imposed body force. As a result the flow-structure interaction between the wake and the torque link was reduced, leading to the attenuation of broadband noise. The noise and flow control performance with the plasma actuators were studied in an anechoic chamber facility as well as in a wind tunnel facility by examining sound pressure and mean flow field respectively. With the current plasma actuators, it was found that there was 1 dB reduction in overall sound pressure level at a free stream speed of 30 m/s, and the wake speed impinging on the torque link was reduced. A possible solution to improve the broadband noise attenuation performance is discussed at the end of this paper.
THE RATIONALITY FOR GOVERNMENT SPONSORED VENTURE CAPITAL FUNDS IN LITHUANIA: INNOVATION PERSPECTIVE

It is widely accepted that early stage SMEs encounter many obstacles which restrict their innovation performance. Limited access to finance is considered as the key obstacle for business development in its early stage. Market failures emerging due to lack of risk capital provision to early stage firms are one of most popular rationality for governments’ intervention in the venture capital market. Following this purpose many countries around the world are launching various public policy schemes in order to diminish lack of supply of capital to early stage SMEs, for instance Yozma in Israel, SBIC in U.S., Labour Sponsored Venture Capital Corporation in Canada and etc. In this paper we refer to government sponsored venture capital fund as a venture capital fund raised from public and private sources in order to meet public policy objectives – to create favourable environment for early stage business development and to give an impetus for innovation creation potential in SMEs.

Comparison of Result Analysis in Weibull Distribution Based on Increasing Right Type Censorship and Hybrid Censorship

In the area of certainty, the pressure-resistance model describes the life of a component that has random resistance X and is subjected to random pressure Y. The component is degraded if the pressure exerted on it exceeds its resistance and will act satisfactorily if {(x, y) }x> y} occurs. Therefore, R = P (X> Y) is a measure of component reliability. Therefore, in this study, we consider the estimation of P (Y <X) based on the second type of sequential censored data and hybrid censorship for both variables. In the first chapter of this study we will examine the relevant definitions and the introduction of the research. In Chapter Two, we review the research on censorship. The third chapter deals with the methodology of the research and finally, the fourth chapter presents the results and discusses them, and the fifth chapter summarizes the research results.
A Study of Simple Partially-Recovered Sensor Data Imputation Methods

We consider the problem of loss of continuous data feeds from sensor networks, due to transient failures. Because the failures are recoverable, part of the missing data may be, eventually, acquired. Even then, the limited resources of the nodes can result in an incomplete reconstruction of the missing data. In this paper we study a set of proposed data imputation methods, and their variations, on a real data set. We determine the tradeoffs involved in the proposed techniques. A common characteristic of the studied techniques is that they depend on the recent behavior of the data stream and do not make specific assumptions about the long-term stochastic behavior of the data. We consider also the case where simple, sub-sampling based, handling of accumulated missing data is implemented by the nodes.
Distributed Leadership in Schools:

Abstract There are ongoing debates about the growing practice of distributed leadership. Research shows that leadership is not only the sole prerogative of the school principal but also other stakeholders who play key roles in leading instructional innovation. This study investigates the extent to which distributed leadership could enhance diverse leadership qualities in schools. Data was collected from two primary and four secondary schools from the Capricorn District in the Limpopo Province of South Africa. Questionnaires were completed by 101 teachers and School Management Teams from the selected six schools. Frequencies were determined by means of spreadsheets engaging the “count if” function. Statistical data was depicted by means of a table and a bar graph to highlight frequencies as well as percentages. Findings reveal that more teachers put their hopes on distributed leadership to engage their leadership skills and eventually enable them to be self-empowered and capacitated.
