Performance Accountability and Combating Corruption (2007)

his volume provides advice on how to institutionalize performance-based accountability, especially in countries that lack good accountability systems. The volume describes how institutions of accountability may be strengthened to combat corruption. The volume is organized into two parts. The first part deals with public management reforms to ensure the integrity and improve the efficiency of government operations. It outlines an agenda for public management reforms and discusses the roles of e-government and network solutions in performance improvements. The second part of the volume provides advice on strengthening the role of representative institutions, such as organs and committees of parliament, in providing oversight of government programs. It also provides guidance on how auditing and related institutions can be used to detect fraud and corruption. The book highlights the causes of corruption and the use of both internal and external accountability institutions and mechanisms to fight it. It provides advice on how to tailor anticorruption programs to individual country circumstances and how to sequence reform efforts to ensure sustainability. This volume presents the latest thinking of leading development scholars on operationalizing such a governance framework. The focus of this volume is creating performance-based accountability and oversight when there is no bottom line. Each chapter addresses an important dimension of such a framework. The four chapters in part I are concerned with integrity and efficiency in public management. The nine chapters of part II are concerned with institutions and mechanisms to hold government to account.
Edge-Detected Guided Morphological Filter for Image Sharpening (2008)

A new edge-guided morphological filter is proposed to sharpen digital images. This is done by detecting the positions of the edges and then applying a class of morphological filtering. Motivated by the success of threshold decomposition, gradient-based operators are used to detect the locations of the edges. A morphological filter is used to sharpen these detected edges. Experimental results demonstrate that the performance of these detected edge deblurring filters is superior to that of other sharpener-type filters.
Mesomorphic Properties of 2-(4-<i>n</i>-Alkoxybenzylideneamino)anthracenes (1977)

Abstract 2-(4-n-Alkoxybenzylideneamino)anthracenes were synthesized, and the phase transitions were determined using a differential scanning calorimeter and a polarizing microscope. Methoxy through propoxy derivatives exhibit the monotropic nematic state, whereas the higher members show the enantiotropic nematic state.
Narrow‐band stripline filters with transmission zeros at finite frequencies (1979)

Abstract A design method is described to realize narrow‐band stripline or microstrip bandpass filters having one transmission zero near to the upper and lower bandedge. The filters utilize capacitively coupled open half‐wave TEM‐line resonators. Two nonadjacent resonators are also inductively coupled. No short circuits are needed. The design is based on the approximate or exact synthesis of the lowpass protoype presented by Levy. The transmission line parameters are obtained easily from the design formulae which have been derived using the susceptance (or reactance) slope parameter technique. The filter performance is good up to 12 per cent bandwidth. Measured results show good agreement with the theoretical ones.

An overview of heavy oil properties and its recovery and transportation methods (2014)

Unconventional oils -mainly heavy oils, extra heavy oils and bitumens -represent a significant share of the total oil world reserves. Oil companies have expressed interest in unconventional oil as alternative resources for the energy supply. These resources are composed usually of viscous oils and, for this reason, their use requires additional efforts to guarantee the viability of the oil recovery from the reservoir and its subsequent transportation to production wells and to ports and refineries. This review describes the main properties of high-viscosity crude oils, as well as compares traditional and emergent methods for their recovery and transportation. The main characteristics of viscous oils are discussed to highlight the oil properties that affect their flowability in the processes of recovery and pipeline transportation. Chemical composition is the starting point for the oil characterization and it has major impact on other properties, including key properties for their dynamics, such as density and viscosity. Next, enhanced oil recovery (EOR) methods are presented, followed by a discussion about pipeline and transportation methods. In addition, the main challenges to achieve viable recovery and transportation of unconventional oils are compared for the different alternatives proposed. The work is especially focused on the heavy oils, while other hydrocarbon solid sources, such as oil sands and shale oil, are outside of the scope of this review.
Structure and function of melanocytes, Microscopic (1995)

Melanocytes characterized by their \n\t\t\t\t tyrosinase activity, melanosomes and dendrites locate \n\t\t\t\t in the basa1 layer of epidermis and hair bulb in the \n\t\t\t\t skin of mice. Melanocytes differentiate from undifferentiated \n\t\t\t\t melanoblasts derived from embryonic \n\t\t\t\t neural crest. Melanocyte-stimulating hormone plays \n\t\t\t\t an important role in the regulation of the differentiation \n\t\t\t\t of mouse melanocytes in the epidermis and hair bulb by \n\t\t\t\t inducing tyrosinase activity, melanosome formation, \n\t\t\t\t transfer of melanosomes and increased dendritogenesis. \n\t\t\t\t The proliferative activity of differentiating \n\t\t\t\t epidermal melanocytes of newborn mice during the \n\t\t\t\t healing of skin wounds is regulated by semidominant \n\t\t\t\t genes, suggesting that the genes are involved in \n\t\t\t\t regulating the proliferative activity of epidermal \n\t\t\t\t melanocytes during differentiation. The morphology and \n\t\t\t\t differentiated functions of mouse melanocytes are \n\t\t\t\t shown to be influenced by environmental factors \n\t\t\t\t such as ultraviolet and ionizing radiations. From \n\t\t\t\t the results of serum-free culture of mouse epidermal \n\t\t\t\t melanoblasts, basic fibroblast growth factor is shown \n\t\t\t\t to stimulate the sustained proliferation of melanoblasts \n\t\t\t\t in the presence of dibutyryl adenosine 3 ' 3 - \n\t\t\t\t cyclic monophosphate and keratinocytes. In contrast, \n\t\t\t\t melanocyte differentiation in serum-free culture \n\t\t\t\t is induced by melanocyte-stimulating hormone \n\t\t\t\t in the presence of keratinocytes. These results \n\t\t\t\t suggest that the structure and function of mouse \n\t\t\t\t melanocytes in the epidermis and hair bulb are \n\t\t\t\t controlled by both genetic factors and local \n\t\t\t\t tissue environment, such as hormones and growth \n\t\t\t\t factors.

Energy Efficient Hybrid Precoding for Multi-User Massive MIMO Systems Using Low-Resolution ADCs (2016)

Millimeter wave (mmWave) communication is an emerging technique to provide large bandwidth in cellular systems. However, mmWave signals experience more pathloss than the microwave signals adopted in current wireless communications. Therefore, a mmWave system tends to adopt a large number of antennas to combat pathloss with high beamforming gain. In conventional multi-antenna systems, both beamforming and precoding are done digitally in baseband. The high cost and power consumption of certain components in mmWave systems render conventional architecture infeasible. In this paper, we consider low complexity hybrid analog/digital precoding and low-resolution ADCs in downlink multiuser mmWave MIMO systems. We propose a new transmission scheme involving rationale of beamspace MIMO communications and beam selection. We also develop a low complexity beam selection algorithm and evaluate adaptive selection on the RF configuration for energy efficiency (EE) optimization. Our analysis and simulation results show that the proposed scheme can significantly reduce system complexity and achieve good performance on energy efficiency and detection.
Path Planning in Unstructured Environments: A Real-time Hybrid A* Implementation for Fast and Deterministic Path Generation for the KTH Research Concept Vehicle (2016)

On the way to fully autonomously driving vehicles a multitude of challenges have to be overcome. One common problem is the navigation of the vehicle from a start pose to a goal pose in an environment that does not provide any specic structure (no preferred ways of movement). Typical examples of such environments are parking lots or construction sites; in these scenarios the vehicle needs to navigate safely around obstacles ideally using the optimal (with regard to a specied parameter) path between the start and the goal pose. The work conducted throughout this master's thesis focuses on the development of a suitable path planning algorithm for the Research Concept Vehicle (RCV) of the Integrated Transport Research Lab (ITRL) at KTH Royal Institute of Technology, in Stockholm, Sweden. The development of the path planner requires more than just the pure algorithm, as the code needs to be tested and respective results evaluated. In addition, the resulting algorithm needs to be wrapped in a way that it can be deployed easily and interfaced with di erent other systems on the research vehicle. Thus the thesis also tries to gives insights into ways of achieving realtime capabilities necessary for experimental testing as well as on how to setup a visualization environment for simulation and debugging.
MPEG2 video parameter and no reference PSNR estimation (2009)

MPEG coded video may be processed for quality assessment or postprocessed to reduce coding artifacts or transcoded. Utilizing information about the MPEG stream may be useful for these tasks. This paper deals with estimating MPEG parameter information from the decoded video stream without access to the MPEG stream. This may be used in systems and applications where the coded stream is not accessible. Detection of MPEG I-frames and DCT (discrete cosine transform) block size is presented. For the I-frames, the quantization parameters are estimated. Combining these with statistics of the reconstructed DCT coefficients, the PSNR is estimated from the decoded video without reference images. Tests on decoded fixed rate MPEG2 sequences demonstrate perfect detection rates and good performance of the PSNR estimation.
Development of a high throughput single nucleotide polymorphism screening method for the cytochrome P450 1A2 polymorphisms CYP1A2*1C and CYP1A2*1F: are they useful as predictive markers in mental disorders? (2010)

This new diagnostic method of multiplex detection may be helpful to routinely identify carriers of CYP1A2 variants and to improve the therapeutic effectiveness by selection of the most appropriate therapeutic regimen. As a result of this pilot study, there appeared to be no significant correlation between the existence of one of the investigated genetic variants and the development of a mental disorder.
Enlarged Block Sizes and Motion Search Ranges for High Definition Video Coding (2007)

A rate-distortion (R-D) model is derived to investigate the potential coding gain from the use of a larger macroblock size for high definition (HD) video coding in this work. Coding rates of using different block sizes for HD video coding are compared with the R-D model, and limitations of the current coding techniques that might impede the additional R-D gain of using enlarged MB for HD coding are explained. Experiments show that an average bit rate gain of 27 % across QP range can be achieved by using enlarged MB and extended motion search range.
Ex vivo gene transfer in the years to come (2002)

Synovial fibroblasts (SFs) have become a major target for ex vivo gene transfer in rheumatoid arthritis (RA), but efficient transduction of RA-SFs still is a major problem. The low proliferation rate and heterogeneity of RA-SFs, together with their lack of highly specific surface receptors, have hampered a more extensive application of this technique. Improving transduction protocols with conventional viral vectors, therefore, as well as developing novel strategies, such as alternative target cells, and novel delivery systems constitute a major challenge. Recent progress in this field will lead to the achievement of high transgene expression, and will facilitate the use of gene transfer in human trials.
Analysis of Buoyancy-Assisted Casings and Liners in Mega-Reach Wells (1992)

ABSTRACT This paper presents an analysis of the drag in extended- and mega-reach wells. An extended-reach well has been defined as any well with a measured depth to true vertical depth ratio (MD/TVD) greater than 2.0. A mega-reach well has a MD/TVD ratio greater than 3.0. The drag while running casing in the mega-reach well can be excessive. This paper investigates various applications of selective floatation devices to reduce the drag on the casing. First, the theoretical foundations of drag analysis for directional wells are reviewed. A methodology for analyzing buoyancy-assisted casing designs is presented. This methodology is used to analyze casing run fully filled with mud, partially filled with mud, and completely floated in mud. In addition, the friction forces during cementing operations are studied. While previous papers were presented on selectively floated casing designs for extended-reach wells, this study goes further to include an analysis of fully and selectively floated liners. In addition, a liner/tie-back combination is compared with the alternative long string casing design. The study concludes that completion of some high angle wells, previously thought unattainable due to high drag, can be achieved using buoyancy-assisted casing programs.
[Blood platelet function, plasma serotonin and lipid metabolism in patients with diabetic nephropathy]. (1995)

Accelerated atherosclerosis is commonly observed in diabetes mellitus as well as in some kidney diseases. This may be partly due to platelet hyperactivity. Serotonin (5-HT) is thought to play a role in platelet/vessel wall interactions and to be implicated in the pathogenesis of atherosclerosis. The aim of the study was to evaluate platelet aggregation and peripheral serotonergic system in patients with diabetic nephropathy. The studies were performed in 37 patients with diabetic nephropathy (age 53.5 +/- 14.9) and healthy volunteers (age 44.2 +/- 12.3). Platelet aggregation (in PRP according to Born) induced by collagen (2 micrograms/ml), ADP (5 microM), epinephrine (10 microM) arachidonic acid (0.25 mM) and 5-HT (1 microM) was found to be significantly enhanced in diabetic relative to controls. Whole blood 5-HT was significantly lower in diabetics patients, whereas plasma 5-HT was significantly higher in diabetic patients when compared to controls. Since serotonin can amplify platelet aggregatory responses to various agonists, platelet hyperactivity in diabetes may be in part due to an enhanced availability of this amine. Disturbances in peripheral serotonergic system together with platelet hyperaggregability may be associated with an increased incidence of cardiovascular complications in diabetes.
철강 산업 관련 근로자에서의 HBsAg 및 Anti - HBs 양성률에 관한 연구 (1993)

The study for positivities of hepatitis B surface antigen (HBsAg) by RPHA and hepatitis B surface antibody (anti-HBs) by PHA and transaminases (SGOT and SGPT) by kinetic method were performed in the months, from March to October 1992 among the steel related industrial workers who were residents of Pohang city. The results were as follows; The positive rate of HBsAg in all subjects was 7.5%, (1089/14472) and that of anti-HBs was 30.7%, (4439/14472). The positivities of HBsAg and anti-HBs in male subjects (7.6%, 30.8%) Were significantly higher than in females (3.7%, 26.3%) (p<0.01. p<0.05 respectively). The positive rates of HBsAg and anti-HBs were increased with age. In males those were significantly higher in their thirties (8.0%, 31.7%) than in their twenties (6.8%, 28.5%) (p<0.05, p<0.001 respectively). The anti-HBs positive rate of females in their forties (54.2%) was significantly higher than that of females in their thirties (29.2%) (p<0.05). The positivities of HBsAg and anti-HBs arrording to educational background or work type in male had no significant differences in either groups (Table 4, 5, 8, 9). There were no significant differences in the positive rates of HBsAg according to the workfield in either groups. But the positive rate of anti-HBs in blue collar workers (31.2%) was significantly higher than that of white co]lar workers (27.0% ) (p < 0.01). 
There were significant differences between the positive rates of HBsAg in males.according to the liver function test (LFT: SGOl and SGPT) which were 6.0% with normal LFT and 21.2% with abnormal LFT (p<0.01). In conclusion, the positive rate of HBsAg was largely influenced by sex, age and LFT but not influenced by educational background, work field or work type. The positive rate cf anti-HBs was largely inflnenced by sex, age and work field but practica@1ly unaffected by educational background or work type.
Precision localization and robust force closure in fixture layout design for 3D workpieces (2002)

Addresses two issues in fixture layout design for 3D workpieces: (1) precision workpiece localization and (2) robust force-closure. An analysis is given to quantify these two fundamental requirements. Based on a concept of optimum experiment design, the optimal fixture design problems are treated to select optimal locators and clamps. An interchange algorithm is described, in which the fixture locators are generated sequentially first and are further improved. The algorithms use multiple criteria to balance the demands for precision localization and robust force closure. Examples are presented to illustrate the issues and to show the effectiveness of the proposed approach.

Camptothecin Accumulation and Variations in<i>Camptotheca</i> (2002)

Camptotheca (Nyssaceae) is a major source of anticancer camptothecin (CPT). It is imperative to understand CPT accumulation and variations in Camptotheca in order to develop CPT production strategies for endangered germplasm. Our study results showed that CPT is primarily accumulated in glandular trichomes of leaves and stems, and CPT content varies among species and varieties but even more significantly within the plant (with different tissues, tissue ages, and seasons). Because of higher CPT yield and desirable biological and ecological features, 'Hicksii' and 'Katie' should be considered the major management germplasm as CPT sources in the future. Young leaves and mature fruits have higher CPT contents than other tissues in the plants. Young photosynthetic leaves and stems contain higher CPT contents than old ones, but 'sink' tissues such as wood, roots, and fruits show different patterns. CPT content also shows a great seasonal change, but is less influenced by tree age. Intact clipping of young leaves and stems should be managed for harvest for CPT production. Preservation and treatment methods influence the CPT extraction. CPT is better preserved in fresh or freeze-dried material than in air or oven-dried material. CPT can be more efficiently extracted after homogenizer treatment of plant materials because more trichome walls can be broken to allow solvent extraction.
