On a Class of High-Girth LDPC Codes Based on Finite Multidimensional Lattices

An LDPC code construction technique is proposed based on the structural properties of finite m-dimensional lattices. The Tanner graph of any code from this class is shown to have a girth of eight, and the number of proper eightcycles in the graph is enumerated. The minimum distance of the codes is shown to be lower bounded by 2. The codes are also shown to be highly flexible in terms of code length and rate, and compatible with a low-complexity serial-parallel decoder implementation based on the turbo-decoding message passing algorithm. Finally, simulation results over the AWGN channel demonstrate that these codes have good error-correcting performance.
PREDICTIVE VALIDITY OF THE IUPUI WEB-BASED PLACEMENT TEST SCORES FOR COURSE PLACEMENT AT IUPUI: 1998-1999

2 Executive Summary This annual report addresses a variety of issues regarding the undergraduate placement tests that are mandated for all entering students at IUPUI. Several changes to the placement testing process were implemented by the academic departments recently, cutoff score modifications to the computerized adaptive math placement test and an experimental procedure for the computerized assessment of writing samples to be used with the high school testing activities (Shermis, Mzumara, Harrington, & Olson, 1998). Based on last year's data, revised placement graphs have been incorporated that indicate the probability of success for a student who achieves a given placement test score (Noble & Sawyer, 1997). We hope that these interpretational aids will provide some additional help to counselors and other academic advisors looking to use the placement tests as one source of information in guiding the student to an appropriate course. The evaluation of the computerized adaptive math test involved samples drawn from fall of 1998 and spring of 1999. A computerized adaptive test is one that conforms to the ability level of the examinee. Several studies have shown this type of test to be just as reliable as the older non-adaptive test, even though it averages to be 30-50% shorter. Our own exit surveys continue to suggest that students like the adaptive tests because they are neither too difficult nor too easy. Moreover, the current computerized adaptive math test, which consists of an item bank of 168 items, addresses security concerns in that each student essentially takes a different form of the test. The placement validity coefficients for this test, calculated on the relationship between the placement test results and a score on a common final, averaged r = . 49, which makes it a very useful predictor and a significant improvement over the last several years. At present, however, the Department of Mathematical Sciences, working with the 3 Testing Center, are engaged in looking at alternative ways to improving the predictive validity of the test, particularly for higher-level courses. Most recently, efforts have been focused on reviewing two of the most popular commercial and nationally-normed placement tests (namely COMPASS and Accuplacer) for possible adoption of either one of the math placement test to address the problem of " under-placement " of students in higher-level math courses. The Indiana-Purdue Computerized Reading Test is modeled after the Nelson-Denny Reading Test, a nationally recognized assessment that is used for placement purposes. …

Comparative Analysis: Energy Efficient Multipath Routing in Wireless Sensor Network

In recent years Wireless Sensor Networks, turn into a famous area of research and development due to the advancement of tiny, cheap, disposable and self-contained battery powered computers, known as sensor nodes or "motes", which can accept input from an attached sensor, process this input data and transmit the results wirelessly to the transit network. One critical concern when scheming wireless sensor network is the routing protocol that makes the best use of the extremely fixed resource presented by WSN, especially the energy bounded. This paper includes the different energy efficient protocols in WSN.
Scheduling Flexible Assembly Systems with Taboo Search Algorithm

A taboo search scheduling algorithm is proposed for scheduling operations of products with intree assembly structure. The neighbor search part of the algorithm takes a "shifting-subtree" technique to avoid incurring infeasible solutions; composed dispatching rules are introduced to get high quality initial solutions, which is critical for taboo search. In addition, parts and corresponding assemblies on the assembly tree are integrated as composite jobs, which simplifies the scheduling program greatly. The computation results validate the effectiveness of the proposed algorithm.
Economic crisis, health systems and health in Europe. Country experiences.

The financial and economic crisis has had a visible but varied impact on many health systems in Europe, eliciting a wide range of responses from governments faced with increased financial and other pressures. This book maps health system responses by country, providing a detailed analysis of policy changes in nine countries and shorter overviews of policy responses in 47 countries. It draws on a large study involving over one hundred health system experts and academic researchers across Europe. Focusing on policy responses in three areas – public funding of the health system, health coverage and health service planning, purchasing and delivery – this book gives policymakers, researchers and others valuable, systematic information about national contexts of particular interest to them, ranging from countries operating under the fiscal and structural conditions of international bailout agreements to those that, while less severely affected by the crisis, still have had to operate in a climate of diminished public sector spending since 2008. Along with a companion volume that analyses the impact of the crisis across countries, this book is part of a wider initiative to monitor the effects of the crisis on health systems and health, to identify those policies most likely to sustain the performance of health systems facing fiscal pressure and to gain insight into the political economy of implementing reforms in a crisis.
The role and use of robust multivariable control in hybrid electric vehicle energy management - Part I: An overview

In this paper, we overview the design and development of robust multivariable control design to highlight some of the pragmatic automotive engineering control issues with an emphasis on a non-trivial application of Hybrid Electric Vehicle (HEV) Torque Management. We shall outline that most existing torque management approaches are not model-based dynamical systems, or do not address key concepts of robust stability and performance. We shall also discuss some advantages that robust control systems could offer to a wider automotive control applications. In part II, we show representative simulation results verifying that robust control systems design could be a breakthrough to the production of hybrid electric vehicles by yielding significant improvements on the emission, fuel consumption, calibration time and cost. Our contribution is aimed at the fact that cutting-edge robust controllers could be broadly adopted to tackle increasingly challenging problems of the automotive industry.
A high-level timing model for variability characterization of interconnect circuits

At nanometer nodes (e.g., 45nm and beyond), stochastic fluctuations on the implemented features and doping levels during the processing of devices is making the electrical parameters of wires and transistors to become more unpredictable, resulting in process variability. Designers cannot neglect the impact of variability on their designs any more, not only during physical design but also during logic synthesis. They need to account for its impact on the timing of the interconnect to make sure that timing closure is achieved and that the design is manufacturable with an acceptable parametric yield. This paper presents a high-level timing model and tool for analyzing typical interconnect circuits accounting for modeling of process variability in the drivers present in the net which is fast enough to be used for Monte-Carlo variability characterization. The approach provides speed-ups between three to four orders of magnitude with very high accuracy when compared to plain SPICE simulation using a 32nn predictive technology model BSIM4 model card
Honest Compressions and Their Application to Compression Schemes

The existence of a compression scheme for every concept class with bounded VC-dimension is one of the oldest open problems in statistical learning theory. Here we demonstrate the existence of such compression schemes under stronger assumptions than nite VCdimension. Specically, for each concept class we associate a family of concept classes that we call the alternating concept classes. Under the assumption that these concept classes have bounded VC-dimension, we prove existence of a compression scheme. This result is motivated by recent progress in the eld of model theory with respect to an analogues problem. In fact, our proof can be considered as a constructive proof of these advancements. This means that we describe the reconstruction function explicitly. Not less important, the theorems and proofs we present are in purely combinatorial terms and are available to the reader who is unfamiliar with model theory. Also, using tools from model theory, we apply our results and prove existence of compression schemes in interesting cases such as concept classes dened by hyperplanes, polynomials, exponentials, restricted analytic functions and compositions, additions and multiplications of all of the above.
A high gain operational amplifier via an efficient conductance cancellation technique

An efficient conductance cancellation method is introduced to achieve high gain operational amplifiers. Without the aid of any tuning circuit, in IBM 130nm CMOS process, the post-layout simulation results show that proposed method is able to maintain a DC gain boost of over 23.2dB under temperatures between -40°C and 80°C, of over 21.1dB under supply voltage between 1.3V and 1.8V, and of over 22.5dB under output voltage swing between 0.1V and 1.3V. The measurement results show that the proposed technique maintains at least 26.4dB DC gain enhancement under output voltage swing between 0.1V and 1.4V, while the power consumption and area overhead of the proposed circuit are respectively less than 2% and 3% of those of the conventional op amps.
Implications of the current trend in mortgage valuation practice in Nigeria

The emerging concern on the reliability of property valuations coupled with the attendant consequences of growing number of distressed banks in Nigeria necessitate this study. Therefore, the study examined the mortgage valuation process including sources of valuation instructions, bases and methods being adopted and their implications on lending decisions and valuation profession in the study area. To accomplish the study, questionnaires were randomly administered on samples of estate surveying and valuation firms and lending institutions respectively in Lagos Metropolis. The data emanating there from were analysed using frequency distributions, ranking mean and relative important index ranking. The study, prima facie, established that mortgage valuation has been an important input in lending decisions. It further showed the implications of the blind adoption of the cost approach, inconsistency amongst valuers and non ‐ inclusion of insurance valuation in the mortgage valuation process.
Stability Analysis of Large-scale Nonlinear Systems with Hybrid Models

This paper proposes a development method to deal with the stability problems for a kind of complex large-scale systems with hybrid models. These hybrid large-scale systems are composed of considerable interconnected nonlinear subsystems, some of which are described by differential equations and others by Takagi-Sugeno fuzzy models. Novel techniques to cope with the nonlinear interconnection between subsystems are developed. A set of LMI-based conditions are derived to judge the stability of the whole system by checking the stability of the subsystems in parallel, which greatly speeds up the stability analysis process. And the computational complexity is greatly reduced. A numerical example is given to illustrate its effectiveness
UAM at INEX 2012 Relevance Feedback Track: Using a Probabilistic Method for Ranking Refinement

This paper describes the system developed by the Language and Reasoning Group of UAM for the Relevance Feedback track of INEX 2012. The presented system focuses on the problem of ranking documents in accordance to their relevance. It is mainly based on the following hy- potheses: (i) current IR machines are able to retrieve relevant documents for most of general queries, but they can not generate a pertinent rank- ing; and (ii) focused relevance feedback could provide more and better elements for the ranking process than isolated query terms. Based on these hypotheses, our participation at INEX 2012 aimed to demonstrate that using some query-related relevance feedback it is possible to improve the final ranking of the retrieved documents.

Questions and answers on design of dual-label microarrays for identifying differentially expressed genes.

The rapid growth in the use of microarrays has generated many questions about how to design experiments that use this technology effectively. Investigators need answers to questions about RNA sample selection, allocation of samples to arrays, robustness of design, dye bias, sample size, and statistical power to ensure that the experimental objectives are achieved. We address some common questions that arise in designing duallabel microarray experiments and provide statistical answers to these questions, focusing specifically on how to select optimal designs for the identification of differentially expressed genes.
Low-Power Photoplethysmogram Acquisition Integrated Circuit with Robust Light Interference Compensation

To overcome light interference, including a large DC offset and ambient light variation, a robust photoplethysmogram (PPG) readout chip is fabricated using a 0.13-μm complementary metal–oxide–semiconductor (CMOS) process. Against the large DC offset, a saturation detection and current feedback circuit is proposed to compensate for an offset current of up to 30 μA. For robustness against optical path variation, an automatic emitted light compensation method is adopted. To prevent ambient light interference, an alternating sampling and charge redistribution technique is also proposed. In the proposed technique, no additional power is consumed, and only three differential switches and one capacitor are required. The PPG readout channel consumes 26.4 μW and has an input referred current noise of 260 pArms.
Measurement Matters for Modeling U.S. Import Prices

We focus on capturing the increasingly important role that emerging economies play in determining U.S. import prices. Emerging market producers differ from others in two respects: (1) their cost structure is well below that of developed-market producers, and (2) their wide profit margins induce pricing policies that seek to exhaust production capacity. We argue that these features have dampened the short-run responses of import prices to changes in the value of the dollar but that they have not altered the associated long-run response. To capture these considerations, we develop a new method to measure foreign prices and adopt a formulation that differentiates between short- and long-run responses. Our econometric work asks two questions: First, can one replicate the literature's dispersion of pass-through estimates? Second, is there any evidence of a change in the dynamic response of import prices to changes in the exchange value of the dollar? To address the first question, we estimate the parameters of our models using several alternative measures of U.S. and foreign prices, dynamic specifications, and sample periods. We find that these alternative inputs translate into a large range of parameter estimates, a finding that helps to rationalizing the existing dispersion of estimates. To address the second question, we compute the implied dynamic adjustment of import prices to a change in the value of the dollar using parameters estimated from two samples: 1974-2000 and 1974-2005. The long-run response of import prices is similar regardless of which sample is used---roughly one-half of the change in the exchange rate is passed through to import prices. However, the short-run response is quite sensitive to the sample period. Specifically, the short-run response based on data through 2005 is smaller than the short-run response based on data through 2000. We argue that one force behind the change in dynamics of the import-price process is the greater presence of producers from emerging economies and that their effect on import prices can be captured with their measure of foreign prices.
Tunable 4-Pole Noncontiguous 0.7–2.1-GHz Bandpass Filters Based on Dual Zero-Value Couplings

This paper presents tunable 2- and 4-pole bandpass filters with a wide tuning range based on dual zero-value couplings. The zero-value coupling is achieved using a coupled line with two coupling paths. The proposed filter also has bandwidth tunability. Frequency and bandwidth tunings are achieved using silicon varactor diodes. Three types of tunable filters are designed and built on a substrate with ε r = 3.55 and h = 25 mil, two filters with two separate frequency bands (2- and 4-pole: Filter A) and one filter with contiguous frequency tuning (4-pole: Filter B). The 2-pole filter results in an insertion loss of 2.9-4.7 dB with a tuning range of 0.75-1.09 and 1.70-2.18 GHz. Filter A with a 4-pole response results in an insertion loss 3.7-7.9 dB and a -1-dB bandwidth of 68-87 MHz with a tuning ranges of 0.77-1.10 and 1.70-2.10 GHz. Filter B shows an insertion loss of 4.4-6.6 dB and a -1-dB bandwidth of 39-68 MHz with a tuning range of 0.70-1.44 GHz. The application areas are in wideband tunable filters requiring contiguous and noncontiguous frequency coverage with bandwidth tunability in separate bands.
What Makes a Good Home-Based Nocturnal Seizure Detector? A Value Sensitive Design

A device for the in-home detection of nocturnal seizures is currently being developed in the Netherlands, to improve care for patients with severe epilepsy. It is recognized that the design of medical technology is not value neutral: perspectives of users and developers are influential in design, and design choices influence these perspectives. However, during development processes, these influences are generally ignored and value-related choices remain implicit and poorly argued for. In the development process of the seizure detector we aimed to take values of all stakeholders into consideration. Therefore, we performed a parallel ethics study, using “value sensitive design. ” Analysis of stakeholder communication (in meetings and e-mail messages) identified five important values, namely, health, trust, autonomy, accessibility, and reliability. Stakeholders were then asked to give feedback on the choice of these values and how they should be interpreted. In a next step, the values were related to design choices relevant for the device, and then the consequences (risks and benefits) of these choices were investigated. Currently the process of design and testing of the device is still ongoing. The device will be validated in a trial in which the identified consequences of design choices are measured as secondary endpoints. Value sensitive design methodology is feasible for the development of new medical technology and can help designers substantiate the choices in their design.
