ASIP Design and Prototyping for Wireless Communication Applications

Last three decades can undoubtedly be said as the decades of wireless communications. New state of the art data processing techniques have been developed and used in practical system. These techniques include advanced Error Control Coding (ECC), Bit Interleaved CodedModulation (BICM), high ordered Quadrature Amplitude Modulations (QAM), Signal Space Diversity (SSD), Multi Input Multi Output (MIMO), Orthogonal Frequency Division Multiplexing (OFDM), and others. To guide the wireless communication industry, for the adoption of new developed techniques in the commercial devices, diverse wireless communication standards have been evolved rapidly in the domain of cellular telephone network, local/wide wireless area networks and Digital Video Broadcast (DVB). These standards propose best combination of evolved data processing schemes at the transmitter to protect data from destructive channel effects under different transmission conditions. Taking an example of mobile telephony, by using newly developed concepts such as spatial multiplexing feature of MIMO, the evolving 3GPP-LTE standard is aimed at achieving 100 Mega bits per second to support high data rate real-time applications on a mobile terminal. Similar trends are also visible in other public domains of wireless communication such as DVB-NGH (Next Generation Handheld), which is the next generation standard for video broadcasting, providing services for fixed and mobile terminals. The other aspect under consideration is the global roaming or seamless coverage across geographical regions which demands multi-mode radios compatible with different systems and standards to provide seamless services at fixed location. While translating these requirements on the physical layer of a radio terminal, this can be seen as a flexible high throughput hardware platform which can be configured to the required air interface. The overall flexibility of the radio platform can be achieved through the flexibility of individual components at transmitter side (encoder, interleaver, mapper, etc.) and at receiver side (equalizer, demapper, deinterleaver, decoder, etc.). This emerging flexibility need in digital baseband design constitutes a new major challenge when added to the ever increasing requirements in terms of throughput and area. In addition to technical requirements associated with rapid growth in wireless communication industry, the severe time-to-market constraints compel the designers for adopting the rapid design, validation and prototyping flow to conceive these wireless radio terminals for their successful and timely delivery in the market. In short, the diverse requirements of wireless communication standards imply, between others, two crucial requirements on hardware implementation: (1) 14
Auditory Spatial Perception: Auditory Localization

Abstract : Research into human auditory localization acuity and factors that compromise this acuity is an ongoing research program at the U.S. Army Research Laboratory. Although there is a wealth of information in the professional literature about the physical, physiological, and psychological underpinnings of auditory localization, the specific theoretical concepts, localization error metrics, and data collection methodologies found in various books and articles are quite diverse and frequently poorly described, making generalizations and data comparison quite difficult. This report is intended to provide information needed to clarify potential methodological and interpretational issues as well as to describe the state of the art in auditory localization science. The specific issues addressed by the report are (1) a common terminological and methodological framework for information exchange regarding localization acuity, (2) the current state of knowledge regarding human localization ability, and (3) various types of localization tasks, measures of localization accuracy and precision, and methods for handling reversal errors. Due to the angular (directional) nature of localization data, a particular focus of the report is the discussion of both circular (spherical) and linear metrics; the statistical methods of data analysis; and the criteria under which a linear analysis of localization data is justified.
A 0.18-μm CMOS 3.5-gb/s continuous-time adaptive cable equalizer using enhanced low-frequency gain control method

This paper describes a high-speed CMOS adaptive cable equalizer using an enhanced low-frequency gain control method. The additional low-frequency gain control loop enables the use of an open-loop equalizing filter, which alleviates the speed bottleneck of the conventional adaptation method. In addition, combined adaptation of low-frequency gain and high-frequency boosting improves the adaptation accuracy while supporting high-frequency operation. The open-loop equalizing filter incorporates a merged-path topology and offers infinite input impedance, which are suitable for higher frequency operation and cascaded design. This equalizing filter controls its common-mode output voltage level in a feedforward manner, thereby improving bandwidth. A prototype chip was fabricated in 0.18-/spl mu/m four-metal mixed-mode CMOS technology. The realized active area is 0.48/spl times/0.73 mm/sup 2/. The prototype adaptive equalizer operates up to 3.5 Gb/s over a 15-m RG-58 coaxial cable with 1.8-V supply and dissipates 80 mW. Moreover, the equalizing filter in manual adjustment mode operates up to 5 Gb/s over a 15-m RG-58 coaxial cable.

Joint Item-Tag Recommendation Framework for Collaborative Filtering in Social Tagging Systems

Tapping into the wisdom of the crowd, social tagging is becoming an increasingly important mechanism for organizing and discovering information on the Web. Effective tag-based recommendation of information items is one of the key technologies contributing to the success of this social information discovery mechanism. A precise understanding of the information structure of social tagging systems lies at the core of an effective tag-based item recommendation method. While most existing methods either implicitly or explicitly assume a simple tripartite graph structure, in this paper, we propose a comprehensive data model to capture all types of co-occurrence information in the social tagging context. Based on this data model, we further propose a unified user profiling scheme to make full use of all available information. Finally, supported by this user profile, we propose a framework for collaborative filtering in social tagging systems. In this framework, we first generate joint item-tag recommendations, with tags indicating topical interests of users in target items. These joint recommendations are then refined by the wisdom from the crowd and projected to the item (or tag) space for final item (or tag) recommendations. Empirical evaluation using real-world data demonstrates the utility of our proposed approach.
User Driven Design: Using Ethnographic Techniques to Plan Student Study Space

Provided with an opportunity to design a new study space for students during a library renovation, librarians and information technologists at Wesleyan University, a small residential campus, teamed up to learn ethnographic techniques and apply them by incorporating student input into the new space, rather than making decisions based on traditional methods. Using this approach produced enlightening information about students' differing behaviors and use of campus space that the team used extensively in planning the new design.

Developing and testing a theoretical framework for assessing extended response questions in GCSE Science

This study aimed to develop, test, and validate a theoretical framework that could be used to write levels-based mark schemes for extended response questions in GCSE science. The work focused on questions which require students to give a scientific explanation or provide an argument. The development was informed by the work of researchers who have evaluated argumentation in the science classroom and also took into account the grade descriptors that are used to determine the cut scores for key grade boundaries during the awards process for GCSE science. The framework was used to write mark schemes for five questions from the January 2012 GCSE Science examinations. The mark schemes were used to mark scripts (n = 19 to 26) from those examinations. The marks awarded were compared with those given by the examiners who originally marked the questions. To ensure the theoretically-based mark scheme could be used by others, three senior examiners also marked two of the questions. Senior assessors (n = 12) for GCSE Science were asked, through an open response questionnaire, to comment on the framework and on its potential usefulness for writing levels-based mark schemes. Comparison of marks awarded using the theoretically-based scheme with those using the original scheme showed that the two schemes produced similar rank orders (Kendall’s coefficient τ = 0.61 to 0.83, n = 19 to 26). When other examiners used the theoretically-based scheme they awarded similar marks to those given by the researcher. These two outcomes suggest that the theoretically-based framework could be used for the proposed purpose. The senior assessors were generally positive about the usefulness of the scheme as a starting position for writing mark schemes and some recognised its potential to provide consistency of standards between different papers in the same session and across time.
Comparison of Routing Protocol AODV and WCETT in Cognitive Radio Network

Cognitive radio is a technology aims to improve the spectrum resource utilization and allows a cognitive radio transceiver to detect and sense spectrum holes without causing interference to the primary users (PUs). Routing in CRN is a challenging task due to the diversity in the available channels. In this paper, Cognitive radio adhoc network (CRAHN) simulation environment is used with AODV and WCETT routing protocols used to address the problem of efficient route selection between the source and destination. The performance of AODV with WCETT protocol is evaluated in CRAHN on the basis of average throughput, average end to end delay, routing overhead and packet delivery ratio. The simulation result shows that performance of WCETT is better than the AODV because of its better route selection strategy in CRAHN. KeywordsCognitive radio, AODV and WCETT.
Message passing in a factored OS

The fos project aims to build a next generation operating system (OS) for clouds and manycores with hundreds or thousands of cores. The key design tenant of fos is to break operating system services into collections of distributed system processes that communicate with message passing rather than shared memory. This microkernelbased design has the potential for better performance and more efficient use of architectural resources. This is because each isolated address space can be scheduled on a separate dedicated core It is anticipated that assigning entire cores to specific system processes will become feasible in the near future given the trend of increasing abundance of cores per die and in the datacenter. Cache locality in particular benefits from this approach, as user applications no longer compete with the operating system for on-core cache resources. However, for such benefits to be fully realized, the message passing system must be sufficiently low latency. Otherwise, too much time will be spent transfering requests between cores. For this thesis, a high-performance message passing system for fos is developed and evaluated. The system supports a variety of messaging mechanisms, including a kernel messaging transport optimized for one-off communications, a low latency user messaging transport tailored to more frequent communications, and inter-machine messaging over TCP network sockets. Experiments show that the user messaging transport can be used to make core-tocore system calls with comparable latency to the trap-and-enter procedure of conventional system calls in monolithic OSes. Thus the latency of messaging to a different core is sufficiently low to allow for the locality benefits of fos's distributed OS services to overshadow any negative impact of messaging costs.

Language teacher education for a global society: A modular model for knowing, analysing, recognizing, doing and seeing

This book aims to empower student teachers/teachers across the globe to base their teaching within context sensitive pedagogy through five modular models for knowing, analyzing, recognising, doing and seeing (KARDS) and ends with the (re)making of a modular model, aiming to look for ‘the patterns that connect’ (p.131).
Collaborative Filtering via Ensembles of Matrix Factorizations

We present a Matrix Factorization (MF) based approach for the Netflix Prize competition. Currently MF based algorithms are popular and have proved successful for collaborative filtering tasks. For the Netflix Prize competition, we adopt three different types of MF algorithms: regularized MF, maximum margin MF and non-negative MF. Furthermore, for each MF algorithm, instead of selecting the optimal parameters, we combine the results obtained with several parameters. With this method, we achieve a performance that is more than 6% better than the Netflix’s own system.
Boosting Multifactor Dimensionality Reduction Using Pre‐evaluation

The detection of gene–gene interactions during genetic studies of common human diseases is important, and the technique of multifactor dimensionality reduction (MDR) has been widely applied to this end. However, this technique is not free from the “curse of dimensionality” — that is, it works well for two‐ or three‐way interactions but requires a long execution time and extensive computing resources to detect, for example, a 10‐way interaction. Here, we propose a boosting method to reduce MDR execution time. With the use of pre‐evaluation measurements, gene sets with low levels of interaction can be removed prior to the application of MDR. Thus, the problem space is decreased and considerable time can be saved in the execution of MDR.
Architectural approaches for code injection defense at the user and kernel levels

Riley, Ryan D. Ph.D., Purdue University, August 2009. Architectural Approaches for Code Injection Defense at the User and Kernel Levels. Major Professors: Dongyan Xu and Xuxian Jiang. Code injection attacks, despite being well researched, continue to be a problem today. Modern architectural solutions such as the execute-disable bit have been use­ ful in limiting the attacks, however they enforce program layout restrictions and can often still be circumvented by a determined attacker. In this dissertation, we analyze the code injection problem from the perspective of a vulnerable system’s memory architecture. We propose an alternative memory architecture, the split memory ar­ chitecture (SMA), which is not susceptible to code injection attacks. This memory architecture can be implemented either in software running on a von Neumann mem­ ory architecture or through slight modifications to the von Neumann architecture. The SMA is also able to support the execution of unmodified programs and operat­ ing systems designed and compiled for a von Neumann system. We demonstrate the efficacy of the SMA approach at the user-level by presenting the design, implementation, and evaluation of an operating system level patch to run a process inside an SMA. The results show that the system is able to prevent a variety of code injection attacks while imposing less than 20% overhead on average. We also demonstrate an SMA at the kernel-level with NICKLE, an instantiation of an SMA in a virtual machine monitor (VMM). We use NICKLE to verify the applicability of the SMA design to the prevention of code injection based kernel rootkits. Our evaluation reveals that NICKLE is able to prevent the execution of these rootkits while imposing less than 10% overhead to QEMU. The VMM-based
A textual and contextual study of English language and literature essays : the case of First Year English Department students' writing in Dhaka University, Bangladesh

This research examines English language and literature essays written by First Year students of the English Department at Dhaka University (Bangladesh) using multi-method genre analysis. The first method used was text analysis. Essay topics were analysed from the two contexts to identify their topic fields and main rhetorical functions. This helped develop the two models to analyse the structure of essays: an Exposition-Discussion model and a Description-Recount model. Then, a total of 100 essays from the two contexts were analysed on the basis of Move-strategy structure to see what structural patterns the essays possessed, what tactical choices the students took to express the moves and what was presented in terms of content matter within those moves. The second method was a questionnaire that was distributed to students in the department to discover their perceptions of the writing tasks given. And the third method was interviews conducted with teachers and students of the department to find out about their perceptions of student writing. This, then, is a genre-based study which draws both on written data and on interaction with community members. The multi-method approach to genre analysis revealed that students of the English Department write three different kinds of essays, Description-Recount language essays, Exposition-Discussion language essays and Exposition-Discussion literature essays. The study further revealed that although students wrote these different kinds of essays, they were unable to make connections between their language essay writing tasks and literature ones because of the disciplinary variations. Moreover, the literature essays were found to be much more challenging to write than the language ones. In the light of this, the need for a fourth type of essay writing is identified. This research contributes to the fields of applied linguistics and education in several ways. Firstly, the models developed not only give insights into the generic structure of the essays students write in the English Department at Dhaka University, but they could also function as a starting point for other researchers working with similar texts. Secondly, the analyses of the high and low grade essays explain how some features of writing are more highly valued than others in this context. Thirdly, the study has pedagogical implications that can benefit students and teachers who would use genre based approach to teaching language and literature essay writing. Fourthly, this research demonstrates a multi-method approach to genre analysis which brings out complementary and sometimes contradictory perspectives on the same written products. Fifthly, it can help university planners and policy makers to consider the relationship between main discipline courses and support courses and minimise any gaps. Finally, it can raise awareness among the global applied linguistics community about the kind of student writing produced in contexts such as the English Department of Dhaka University.
Evaluation of E-CMS Using Tam: Focusing on Lecturer Acceptance

Characteristic of modern academic institutions is the utilization of information technology (IT) in the educational activities, including implementation of electronic course management systems (e-CMS). It provides various roles that support institutions staffs to achieve effective and efficient way of teaching. There are several factors that affect e-CMS‘ implementation, for instance support from university, the characteristics of the specific e-CMS application, and the acceptance of users. The acceptance of lecturers as one of e-CMS‘ main user is critical to determine the acceleration of the e-CMS implementation. The objective of this paper is to evaluate e-CMS implementation in Petra Christian University (PCU) by focusing on lecturers‘ acceptance of e-CMS. The Technology Acceptance Model (TAM) framework utilized for the evaluation process. The study found that perceived usefulness is the major concern of Petra Christian University‘s (PCU) lecturers in their attitude and acceptance to use e-CMS. The Partial Least Squares (PLS) analysis employed to analyze the structural model in this research.
