Hardware architectures for PRESENT block cipher and their FPGA implementations

Data security is essential for the proliferation of the Internet of things and cyber-physical system technologies. Data security can be efficiently achieved by incorporating lightweight cryptography techniques. In this study, a set of high-performance hardware architectures for PRESENT lightweight block cipher are proposed that perform encryption, decryption and integrated encryption/decryption operations. Datapath of the architectures is of 64 bit width that supports standard 80 and 128 bits key lengths. The architectures are synthesised on Xilinx Virtex-5 XC5VLX110T (ff1136-1) field-programmable gate array device of ML-505 platform. To perform functional verification, a large number of test vectors are used. Performance measurement is performed by evaluating maximum frequency, throughput, power dissipation and energy consumption. Experimentally, it is found that the proposed architectures are resource-efficient, high-performance and suitable for lightweight, latency-critical and low-power applications in comparison with existing architectures.
In situ synthesis of novel biomass lignin/silica based epoxy resin adhesive from renewable resources at different pHs

Abstract Novel biomass lignin/silica composites were prepared and isolated from rice husk renewable resources at different pHs. Selective precipitation was achieved by decreasing the solution pH from 9.5 to 1.5. When pH reached 3.5, the ratio of lignin and silica mostly achieved the maximum of 1:1. We selected lignin/silica composites as reactants to replace 20 wt% bisphenol A in preparing epoxy resin. The cured novel biomass function lignin/silica-based epoxy resin adhesive showed the highest adhesive strength up to 2.68 MPa, which displayed 123% of neat epoxy resin adhesive. In addition, lignin/silica composites were depolymerized through the hydrothermal method by NaOH as a catalyst, which was used as reactants to replace 35 wt% bisphenol A in the process of in situ synthesis of epoxy resin adhesive. At this point, the high epoxy value (1.42 wt%) and large adhesive strength (3.98 MPa) of lignin/silica-based epoxy resin adhesive were obtained, which adhesive strength was 183% of neat epoxy resin adhesive. The results demonstrated that depolymerized lignin/silica-based epoxy resin adhesive showed the higher epoxy value and the adhesive strength compared with neat epoxy resin adhesive and lignin/silica-based epoxy resin adhesive. Their function in epoxy matrix resulted in better processability.
Embedded Wafer Level Ball Grid Array (eWLB)

The main challenges of today's device packaging are miniaturization, continuously increasing operating frequencies/high data rates, high number of I/Os, reliability, and thermal requirements. One of the major package trends driven by mobile-phone applications is the Wafer Level Ball Grid Array (WLB). Drivers for the implementation of WLB technology are cost reduction, smaller form factor and better electrical performance with respect to high frequency applications. Thin-film WLB technology consists in realizing additional redistribution layers above the passivation of a semiconductor chip using standard thin-film techniques to rearrange peripheral pads on the wafer in an array pattern. A hard limit will be reached with this technology, when the number of I/Os reaches a larger number dian can be fitted on the silicon chip at a given pitch. We introduce Infineon's embedded Wafer Level Ball Grid Array technology, which allows fitting interconnects onto a so-called fan-out area extending the chip area. The core process of this emerging technology is the encapsulation of silicon dice by compression molding. The eWLB technology is a forward-looking development of the WLB technology, upholding the known benefits such as small package dimensions, excellent electrical and thermal performance, and maximum connection density. However, this technology significantly increases the functionality and application spread. Due to eWLB. complex semiconductor chips such as modem and processor chips for applications in mobile communications require a high number of solder connections with standardized contact spacing to be produced with a minimal footprint. At the same time, the packages can be provided with as many solder contacts as needed. The possibility of additional wiring area around the chip proper means that the wafer-level packaging technology also lends itself to new. space-sensitive applications. We demonstrate the capabilities of Infineon's molded embedded Wafer Level Package Technology and show how we extended it towards a Platform Technology. The qualified Platform we introduce here covers currently a range of package sizes up to 8×8mm2 at a ball pitch of 0.5mm. The Qualification Criteria we have applied follow the tests described in JEDEC Standard Number 26-A.

Competitive warm-up in basketball: literature review and proposal

Resumen El calentamiento es utilizado, aceptado y practicado previamente a la realización de una práctica deportiva por la totalidad de sus participantes. Además, es considerado imprescindible para alcanzar un rendimiento óptimo por la mayoría de deportistas. Sin embargo, existe poca evidencia científica que apoye su efectividad. Todo esto, junto con la diversidad de los deportes, hace necesario la estandarización de unas pautas comunes de calentamiento para cada deporte o disciplina deportiva. En cuanto al baloncesto de élite se refiere, hemos encontrado un gran vacío científico que nos gustaría cubrir. Por lo tanto, los objetivos de este artículo son, primero, la realización de una revisión bibliográfica sobre todos los aspectos relacionados con el calentamiento como pueden ser: definición de calentamiento, tipos de calentamientos, beneficios del mismo, estructura que debe seguir (intensidad, duración, recuperación y especificidad), factores que influyen sobre él, estiramientos si o estiramientos no y de qué tipo en el calentamiento. Y segundo, con las conclusiones obtenidas, describir y proponer una metodología de calentamiento competitivo adaptado al baloncesto de alto nivel, para que ésta se convierta en una guía de referencia justificada a la hora de realizar esta fase pre-partido.
Novel secondary radar for precise distance and velocity measurement in multipath environments

The performance of wireless systems strongly depends on the characteristics of the radio channel. Multipath propagation and Doppler effect are two phenomena to be considered. We present a frequency-modulated continuous wave (FMCW) secondary radar concept to estimate the offset in time and in frequency of two wireless units and to measure their distance to each other. The distance can be measured with a standard deviation as low as 1 cm. However, the accuracy of the system is degraded in multipath environments or if the stations are moving relative to each other. In this paper we show a novel extension of the algorithm to cope with multipath propagation and the Doppler effect. The broadband measurement principle at hand is robust towards multipath interference. Additionally the Doppler effect is compensated for. By evaluating the Doppler frequency shift the relative velocity of the mobile units is measured directly. Measurement results prove the significant improvement in system performance if the extended algorithms are used.
EVALUACIÓN DE ACTITUDES VIOLENTAS Y CLIMA ESCOLAR EN SITUACIONES DE AGRESIVIDAD EN ALUMNADO DE SECUNDARIA

The present work is framed in the central phase of an investigation in Secondary Education (Research DGES BSO2000-1199 directed by Dra. Trianes from Malaga University, Spain). The main objective of this study consists on analysing the interactions pupil-institute and the disruptive behaviours and aggressive in Institutes with an adaptation of the Scale of School Climate of Furlong and cols. (1991). The first results of the application of this test are presented. A sample of 548 students of 2o and 3o of Obligatory Secondary Education has been tested, coming from five Institutes of Malaga (Spain). The data were analysed at descriptive level (frequency for item and reliability, from a previous factorial analysis).
Primary Voltage Control in Active Distribution Networks via Broadcast Signals: The Case of Distributed Storage

Summary form only given. In this paper we consider an active distribution network (ADN) that performs primary voltage control using real-time demand response via a broadcast low-rate communication signal. The ADN also owns distributed electrical energy storage. We show that it is possible to use the same broadcast signal deployed for controlling loads to manage the distributed storage. To this end, we propose an appropriate control law to be embedded into the distributed electrical storage controllers that reacts to the defined broadcast signal in order to control both active and reactive power injections. We analyze, in particular, the case where electrical storage systems consist of supercapacitor arrays and where the ADN uses the Grid Explicit Congestion Notification (GECN) for real-time demand response that the authors have developed in a previous contribution. We estimate the energy reserve required for successfully performing voltage control depending on the characteristics of the network. The performance of the scheme is numerically evaluated on the IEEE 34-nodes test feeder. We further evaluate the effect, depending on the line characteristics, of reactive versus active power controlled injections. We find that without altering the demand-response signal, a suitably designed controller implemented in the storage devices enables them to successfully contribute to primary voltage control.
Evaluation of Multicast Routing Algorithms for Real-Time Communication on High-Speed Networks

Multicast (MC) routing algorithms capable of satisfying the quality of service (QoS) requirements of real-time applications will be essential for future high-speed networks. We compare the performance of all of the important MC routing algorithms when applied to networks with asymmetric link loads. Each algorithm is judged based on the quality of the MC trees it generates and its efficiency in managing the network resources. Simulation results over random networks show that unconstrained algorithms are not capable of fulfilling the QoS requirements of real-time applications in wide-area networks. Simulations also reveal that one of the unconstrained algorithms, reverse path multicasting (RPM), is quite inefficient when applied to asymmetric networks. We study how combining routing with resource reservation and admission control improves the RPM's efficiency in managing the network resources. The performance of one semiconstrained heuristic, MSC, three constrained Steiner tree (CST) heuristics, Kompella, Pasquale, and Polyzos (1992), constrained adaptive ordering (CAO), and bounded shortest multicast algorithm (BSMA), and one constrained shortest path tree (CSPT) heuristic, the constrained Dijkstra heuristic (CDKS) are also studied. Simulations show that the semiconstrained and constrained heuristics are capable of successfully constructing MC trees which satisfy the QoS requirements of real-time traffic. However, the cost performance of the heuristics varies. The BSMA's MC trees are lower in cost than all other constrained heuristics. Finally, we compare the execution times of all algorithms, unconstrained, semiconstrained, and constrained.
Lower than best effort: a design and implementation

In recent years, the Internet architecture has been augmented so that Better-than-Best-Effort (BBF) services, in the form of reserved resources for specific flows, can be provided by the network. To date, this has been realized through two different and sequentially developed efforts. The first is known as Integrated Services and focuses on specific bounds on bandwidth and/or delay for specific flows. The Differential Service model was later introduced, which presented a more aggregated and local perspective regarding the forwarding of traffic. A direction that is missing in today's work on service models is a defined schema used to purposely degrade certain traffic to various levels below that of Best Effort. In a sense, a new direction that provides a balancing effect in the deployment of BBE service. This is particularly evident with continual and parallel short transaction flows (like that used for web applications) over low bandwidth links that are not subject to any backoff penalty incurred by congestion because state does not persist. In a more indirect perspective, our model correlates degraded service with the application of usage and security policies — administrative decisions that can operate in tandem or disjointly from conditions of the network. This paper attempts to address these and other issues and presents the design and implementation of such a new degraded service model and queuing mechanism used to support it.
An Assessment of the Employee Job Satisfaction: Views from Empirical Perspectives

Job satisfaction stresses on the personal feelings within the job environment in relation to job assessment. Various academics and scientists studied in the past, the significant association between personal expectations and job satisfaction of employees. These past studies were based on the model of personality traits and other variables in determination of employee job satisfaction. This study is to assess the relationship and effect between independent and dependent variables. To ensure that the stated objectives are met, a 7 point Likert scale questionnaires were administered to 140 managers and non-manager employees. However, only 128 of the questionnaires were returned without errors and ready to go through the analysis processes. Data analysis was conducted in two phases namely the descriptive and inferential statistics. Descriptive analysis aided by the mean counts was applied in describing the empirical data; whereas the inferential statistics of Pearsonâ€™s chi-square test and ANOVA were utilized to determine the relationship and the effect of independent on the dependent variable. ANOVA was used to assess the effect of independent variables on the dependent variable. This empirical study demonstrates mix results through Pearsonâ€™s chi-square and ANOVA tests. WEP and employee status does not differ from EJS whereas employee position differs from EJS. The ANOVA test revealed a significant effect of WEP and EPS on EJS. The study revealed that SME owners in FB district municipality experienced very high entrepreneurial challenges in contrast to their counterparts in JTG district municipality. Given these findings, the author called on policymakers to prepare specific strategies and programs that motivate employees within the establishment.
An Investigation of Monitoring Frequency and Slack Allowance on Reporting Honesty

ABSTRACT Businesses that use participative budgeting commonly face the problem of subordinates introducing budgetary slack into the planning process in a manner that harms the organization. This study examines budgetary reporting behavior in response to two key features of a monitoring system, the frequency of monitoring (increasing versus decreasing) and thresholds in a monitoring system that determine an allowable level of budgetary slack (low versus high slack allowance). Based on prior theory and literature, we develop hypotheses and research questions regarding the effects of these monitoring features on subordinates’ slack creation. We test our predictions in a multiple-round experimental setting that uses economic incentives. Participants’ actions are consistent with the strategic creation of slack to maximize wealth (to the extent permitted given the constraints of the monitoring system) rather than preferences for honesty. Of the monitoring systems imposed, a low slack allowance combined with high monitoring frequency that decreases over time is most effective in reducing slack creation.
The Play’s the Thing: Associations between Make-Believe Play and Self-Regulation in the Tools of the Mind Early Childhood Curriculum

ABSTRACT Make-believe play has been theorized to promote self-regulation skills and other positive child outcomes. In this study, we examine the make-believe play approach featured in the Tools of the Mind (Tools) early childhood curriculum, which identifies students’ self-regulation cultivation among its core programmatic aims. Using data from 42 classrooms in the United States, we specified latent growth models to investigate the association between Tools make-believe play and children’s self-regulation development throughout pre-kindergarten, kindergarten, and first grade (N = 646 students aged between four and seven years old). We found that higher implementation frequency and fidelity of Tools play predicted less self-regulation growth. Implications for policy and practice are discussed.

Moreover, studies on the influential factors of semantic inferences show that semantic inferences are not only affected by contextual constraints, but also closely related to processing strategies. Keywords—bridging inferences; elaborative inferences; influential factors; working memory capacity
Source-code Similarity Detection and Detection Tools Used in Academia

Teachers deal with plagiarism on a regular basis, so they try to prevent and detect plagiarism, a task that is complicated by the large size of some classes. Students who cheat often try to hide their plagiarism (obfuscate), and many different similarity detection engines (often called plagiarism detection tools) have been built to help teachers. This article focuses only on plagiarism detection and presents a detailed systematic review of the field of source-code plagiarism detection in academia. This review gives an overview of definitions of plagiarism, plagiarism detection tools, comparison metrics, obfuscation methods, datasets used for comparison, and algorithm types. Perspectives on the meaning of source-code plagiarism detection in academia are presented, together with categorisations of the available detection tools and analyses of their effectiveness. While writing the review, some interesting insights have been found about metrics and datasets for quantitative tool comparison and categorisation of detection algorithms. Also, existing obfuscation methods classifications have been expanded together with a new definition of “source-code plagiarism detection in academia. ”

Scaling trends and challenges of advanced memory technology

Summary form only given. DRAM and NAND technologies have been successfully developed so far thanks to advanced patterning and device technologies, meeting high density, high performance and low cost requirements. However, imminent scaling limit in DRAM and NAND requires breakthrough technologies to meet market needs. DRAM technology in 1xnm and beyond faces severe challenges, such as difficulties in obtaining sufficient storage capacitance and sensing margin. To alleviate the problems, new materials for cell capacitor should be exploited and systematic aids such as error correction should be considered. Besides these scaling issues, DRAM has been suffering from performance issue, and it requires enhanced peripheral transistor performance with low power and high speed by using new process technologies such as HKMG. A 3D integration with TSV provides a new solution for high density, high speed, low power, and wider bandwidth without traditional device geometric scaling. However, 3D has its own challenges such as high manufacturing cost and reliability that need to be overcome before it could be widely used. 3D NAND flash memory technologies have been studied as a strong contender due to their potential for replacing conventional 2D floating gate cell. Recently, there has been remarkable progresses towards mass production even though their inherent issues of poor data retention and process complexity. Several challenges such as process, material, and cell architecture will be discussed. New non-volatile memories such as ReRAM, PRAM and STT-MRAM have undergone explosive study in the past decade. ReRAM and PRAM are now leading candidates to replace conventional NAND or NOR flash memories and to pioneer the field of Storage Class Memories, while STT-MRAM is regarded as the only a non-volatile memory that can have the performance of DRAM due to its high-speed read/write and excellent cycling endurance. Device characteristics of new non-volatile memories, key technology of device integration and materials will be discussed.
Paradigma inmunológico en la fase intestinal de Trichinella spiralis

Las nematodosis intestinales afectan actualmente a casi un billon de personas, siendo una de las enfermedades infecciosas mas prevalentes. Estan asociadas con un curso cronico y altos niveles de morbilidad y discapacidad. Durante la evolucion, han adquirido medios sofisticados de adaptacion que les ha permitido, mediante la utilizacion de una serie de mecanismos, la supresion o evasion del sistema inmune con el fin de sobrevivir. De manera general, los nematodos gastrointestinales ponen en marcha una respuesta Th2 en el hospedador y estan asociadas con una disminucion de las enfermedades autoinmunes. Trichinella spiralis es un nematodo gastrointestinal ampliamente distribuido. A diferencia de los demas nematodos gastrointestinales, no sigue el modelo comun de respuesta Th2. Esto es asi, debido a su diferencia de localizacion intestinal. Tras su entrada se desencadena una respuesta Th1 y tras ponerse en marcha la fase migratoria y muscular, se desencadena una respuesta Th2 que pondra fin a la fase intestinal y la expulsion de los adultos del intestino. Su capacidad inmunomoduladora esta siendo objeto de una intensa actividad investigadora y se ha visto su posible utilizacion como herramienta terapeutica en numerosas enfermedades autoinmunes
