A dynamic locality optimization algorithm for linear algebra codes

Compiler-directed optimization techniques are e ectiv e in reducing the number of cycles spent in o -c hip memory accesses. Recently, methods have been developed that transform memory layouts of data structures at compile-time to improve spatial locality of nested loops beyond current con trol-cen tric (loop nest-based) optimizations.Most of these data-cen trictransformations use a single static (programwide) memory layout for each array. A disadv an tageof these static la yout-based localit y enhancement strategies is that they might fail to optimize codes that manipulate arrays whic hdemand di erent layouts (from a data locality perspectiv e) in di erent parts of the code. In this paper, we presen t a new approach which extends curren t static layout optimization techniques to select dynamically changing memory layouts to further improve the locality of data accesses. We show that the possibilit yof dynamically changing memory layouts during the course of execution adds a new dimension to the data locality optimization problem. Our strategy employs a static layout optimizer module as a building block and by repeatedly invoking it for di erent parts of the code, it checks whether run time layout modi cations bring additional bene ts beyond static optimizer.
Linear Analysis Method for Scheduling Problems

A linear analysis method is given out to analysis real-time scheduling problems, including periodic task scheduling, schedulability analysis and so on. By define Time Segment (TS) of hyper period, we deduced a group of equations which can represent real-time constraints. Next, transform the group of equations into linear equation problem and linear programming problem, which are used to precisely calculate the scheduling problems by mathematical methods.
Parallel context aware recommender system using GPU and JCuda

Recommender Systems (RS) are intelligent applications which predict the preferences for users from their current interests. Collaborative Filtering (CF) is a widely used Recommendation technique. On large scale data, collaborative filtering approach is very time consuming and hence parallel processing can be useful for accelerating the task of recommendation. Context Aware Recommender Systems (CARS) help us to generate precise and relevant recommendations by using specific context of the user. This paper presents Parallel Context Aware CF Recommender Systems using JCuda (PCARS) that involves Graphic Processing Unit (GPU). The proposed algorithm works in two phases: offline and online processing. Two kernels are identified and processed for offline processing which reduce the processing time drastically. Online processing involves with the prediction calculation for the items which is not yet seen by target user and can be recommended to them. Offloading the prediction calculation to GPU will help to increase the overall system performance significantly. A prototype of the proposed system is developed using JCuda, CUDA and Java technologies for the restaurant domain. The performance of the proposed system PCARS is compared to the Collaborative Filtering Recommender Systems (CFRS) without parallel processing using contextual pre-filtering and context post-filtering in terms of processing time. Experimental results demonstrated the tremendous speedup of the system over a single-core CPU based system.

Mining images for image annotation using SURF detection technique

Image annotation is a method to title a particular image. The image annotation scheme would create a scenario in which a set of images are provided as training set. The query image is then identified and properly annotated, by matching the features of the query image and the existing training set images and correspondingly labels are provided. This work aims at working on the annotation of different types of images using training set images, the approach is to calculate the feature set of the training set images and saving them into an array. The query images feature set is also calculated and compared with that of the existing ones, the one with more matching features would be highlighted and the corresponding label of that particular image is provided to the query image. The analysis of this particular technique is performed with large number of test image sets for better accuracy.
Models for Estimating the Output Gap: Application to the GDP of Dominican Republic.

This document compares the proprieties of different empirical methodologies to estimate the output gap and the potential output (non-observable variables of interest to the design of monetary policy and macroeconomic analysis) using Dominican Republic as a case of study. The output gap and potential output are estimated with three different methods: univariated filters, non-observable variables methodology; and structural autorregresive vector (SVAR). Also, using all measures of output gap, a Phillip’s curve is estimated with each measure to evaluate the usability of these in macroeconometric models of policy analysis and forecast. 1 JEL: C32, C53, E37 2 f.ramirez@bancentral.gov. do Los puntos de vista expresados son los del autor y no comprometen los del Banco Central de la República Dominicana.

Effects of interplant defence signalling on production and allocation of biomass

Barley plants are known to release volatiles, both when infested by aphids and uninfested. Neighbouring barley plants have in previous studies been seen to induce a defence mechanism against aphids when exposed to these volatiles. In this study investigated whether volatiles from aphid infested barely plants as well as two chemicals, methyl jasmonate and methyl salicylate, affect biomass allocation and growth of exposed plants. In order to accomplish this, a first experiment was done in which barley cultivars Alva and Kara were infested by aphids. Other, uninfested, Kara plants were exposed to air from the aphid-infested plants. Plant samples were taken at five occasions and growth parameters were calculated. No changes in total dry weight were seen between the treatments and control plants and no changes in biomass allocation appeared. A second experiment was conducted, in which Kara plants were exposed to volatiles from methyl salicylate and methyl jasmonate. These two chemicals are thought to be involved in volatile communication between plants and have been shown to induce defence against aphids in barley plants. No change in total dry weight or biomass allocation was found after exposure to the chemicals. The results suggest that the induced defence in barley plants exposed to aphid infested barley plants, methyl salicylate or methyl jasmonate does not correlate with green plant biomass costs.
High-level hierarchical semantic processing framework for smart sensor networks

This paper presents the framework of a novel approach to combine multi-modal sensor information from audio and video modalities to gain valuable supplementary information compared to traditional video-based observation systems or even just CCTV systems. A hierarchical, multi-modal sensor processing architecture for observation and surveillance systems is proposed. It recognizes a set of pre-defined behavior and learns about usual behavior. Deviations from ldquonormalityrdquo are reported in a way understandable even for staff without special training. The processing architecture including the physical sensor nodes is called SENSE (smart embedded network of sensing entities) (Zucker and Frangu, 2007).
Transformational Leadership, Behavioral Habituation to Build the Character of a Leader

—Currently, an organization will be seen as a reflection of its leaders, including organizations in the field of education. A successful organization can mean that a leader is successful in it. A successful leader is judged not only by his position or power but by focusing on his character, behavior, and actions so that he is seen as an effective leader. This study aims to 1) know the pattern of behavior habituation so as to shape the character of a leader 2) form a conceptual frame of mind how behavior habituation can shape the character of an effective leader. This framework of thinking focuses more on the habitual pattern of thinking of a leader in an organization or educational institution. This study used a descriptive qualitative approach. Data collection techniques used are observation, interviews, and document study. The results of the study are then compiled into a mindset which is a habitual habituation instilled in the educational environment so as to shape the character of an effective leader. This mindset includes self-habituation, habituation in the environment, and habituation of synergy to form the character of a transformational leader as a vision builder, motivator, stimulator, and inspiration for his subordinates.
Områdesbaserad politik för minskad segregation : En studie av den svenska storstadspolitiken

In the beginning of the 1990s Sweden entered an economic recession. The subsequent negative economic and social consequences appeared more and more acute. The issue of residential segregation appeared on the political agenda and the Swedish metropolitan policy was launched in 1998. As in other West European countries an area-based development programme, the Local development agreement, was initiated. The aim of this thesis is to examine the area-based strategy in relation to the political aim to stop segregation.Document analyses and interviews have been conducted to discover ideas within the public policy, among researchers and civil servants about problem, causes and solutions. The practical experience of civil servants in working with the area-based programme and in partnerships is also studied. Trough a quantitative analysis the situation in four distressed neighbourhoods is described and the selectivity of the programme within the municipalities is examined. Study areas are the neighbourhoods of Husby and Tensta in the city of Stockholm, as well as Hjallbo and Norra Biskopsgarden in the city of Gothenburg.The thesis identifies possibilities and limitations with an area-based strategy as an anti-segregation strategy. Against this background the potential of the area-based strategy to stop segregation are investigated. Results show that measures in distressed neighbourhoods are needed and that an area-based policy has potential effects on living conditions in distressed neighbourhoods and on individual life chances. That an area-based policy will stop segregation is, however, unlikely.
MORPHOLOGIC VARIATION IN PNEUMOCOCCUS

The interaction of each of the four morphologic variants of pneumococcus with the transforming principles of the heterologous morphologic variants of the same species has been studied and has resulted in the isolation of eighteen of the twenty variants predicted to arise through such interactions. The analogy of the findings to the recombination of independently heritable characters in sexually reproducing forms has been noted.
Strongly meager sets and their uniformly continuous images

We prove the following theorems: (1) Suppose that f; 2W 2W is a continuous function and X is a Sierpiiiski set. Then (A) for any strongly measure zero set Y, the image f[X + Y] is an so-set, (B) f [X] is a perfectly meager set in the transitive sense. (2) Every strongly meager set is completely Ramsey null. This paper is a continuation of earlier works by the authors and by M. Scheepers (see [N], [NSW], [S]) in which properties (mainly, the algebraic sum) of certain singular subsets of the real line R and of the Cantor set 2' were investigated. Throughout the paper, by a set of real numbers we mean a subset of 2' and by "+" we denote the standard modulo 2 coordinatewise addition in 2W. Let us also assume that a "measure zero" (or "negligible") set always denotes a Lebesgue measure zero set. We apply the following definition of sets of real numbers. Definition 1. An uncountable set X is said to be a Luzin (respectively, Sierpin'ski) set iff for each meager (respectively, measure zero) set Y, XnY is at most countable. We say that a set X is of strong measure zero (respectively, strongly meager) iff for each meager (respectively, measure zero) set Y, X + Y 7& 2'. Remark 1. It is well known (see [M] for example) that every Luzin set is strongly measure zero. Quite recently J. Pawlikowski proved that each Sierpin'ski set must be strongly meager as well (see [P]). Let us recall that a set X is called an so-set (or Marczewski set) iff for each perfect set P one can find a perfect set QCP that is disjoint from X. M. Scheepers showed in [S] that for a Sierpin'ski set X and a strong measure zero set Y, X + Y is an so-set. Later, in [NSW] it was proven that this also holds when X is strongly meager. We have the following functional version of the M. Scheepers' result. Theorem 1. Let X be a Sierpin'ski set and let Y be a strong measure zero set. Assume also that f: 2' -* 2W is a continuous function. Then the image f[X + Y] is an so-set.

Soil erosion by snow gliding - a first quantification attempt in a subalpine area in Switzerland

Snow processes might be one important driver of soil erosion in Alpine grasslands and thus the unknown variable when erosion modelling is attempted. The aim of this study is to assess the importance of snow gliding as a soil erosion agent for four different land use/land cover types in a subalpine area in Switzerland. We used three different approaches to estimate soil erosion rates: sediment yield measurements in snow glide depositions, the fallout radionuclide 137 Cs and modelling with the Revised Universal Soil Loss Equation (RUSLE). RUSLE permits the evaluation of soil loss by water erosion, the 137 Cs method integrates soil loss due to all erosion agents involved, and the measurement of snow glide deposition sediment yield can be directly related to snow-glide-induced erosion. Further, cumulative snow glide distance was measured for the sites in the winter of 2009/2010 and modelled for the surrounding area and long-term average winter precipitation (1959–2010) with the spatial snow glide model (SSGM). Measured snow glide distance confirmed the presence of snow gliding and ranged from 2 to 189 cm, with lower values on the north-facing slopes. We observed a reduction of snow glide distance with increasing surface roughness of the vegetation, which is an important information with respect to conservation planning and expected and ongoing land use changes in the Alps. Snow glide erosion estimated from the snow glide depositions was highly variable with values ranging from 0.03 to 22.9 t ha −1 yr −1 in the winter of 2012/2013. For sites affected by snow glide deposition, a mean erosion rate of 8.4 t ha −1 yr −1 was found. The difference in long-term erosion rates determined with RUSLE and 137 Cs confirms the constant influence of snow-glide-induced erosion, since a large difference (lower proportion of water erosion compared to total net erosion) was observed for sites with high snow glide rates and vice versa. Moreover, the difference between RUSLE and 137 Cs erosion rates was related to the measured snow glide distance ( R 2 = 0.64; p R 2 = 0.39; p = 0.13). The SSGM reproduced the relative difference of the measured snow glide values under different land uses and land cover types. The resulting map highlighted the relevance of snow gliding for large parts of the investigated area. Based on these results, we conclude that snow gliding appears to be a crucial and non-negligible process impacting soil erosion patterns and magnitude in subalpine areas with similar topographic and climatic conditions.
Unsupervised Change-Detection in Color Fundus Images of the Human Retina

The aim of this paper is to develop an automatic method for the detection of the changes that occurred in multitemporal digital images of the fundus of the human retina, in terms of white and red spots. The images are acquired from the same patient at different times by a color fundus camera. The proposed approach is unsupervised and is based on a minimum-error thresholding technique. This technique is applied both to separate the "change" and the "no-change" classes in a suitably defined difference image, and to distinguish among different typologies of change. The algorithm is tested on 10 multitemporal pairs of images. A quantitative assessment of the change detection performances suggests that the method is able to provide accurate change maps, although possibly affected by misregistration errors or calibration/acquisition artifacts
Bi-Level Agent Hierarchies ( BLAH ) : A Double-Layered Formalization for Learning and Communication in Multi-Agent Systems

Simulations have become a great tool for research in the natural sciences. However their potential has not been reached in the social sciences. This is in part due to the difficulty in simulating human decision making. Recent advances in neo-classical decision making have defined specific differences between the decision making capabilities of rational agents and humans as well as speculations into the cause. Presented in later sections is a proposition for the formalization of a model for simulating human decision making as well as a method for verifying the method. The flip-side of the social simulation coin requires an examination of systemic pressures and conditions that affect individual agents. In order to formally model such systemic factors, various social metrics must be devised. Specifically, we will go on to examine the issue of simulated social influence. The trouble with metrics that seek to approximate influence across a network is that such metrics are potentially two-sided: agent a might have a high degree of potential influence which a does not actually use. Both of these metrics can be interesting and useful.
HIGH-REDSHIFT COOL-CORE GALAXY CLUSTERS DETECTED VIA THE SUNYAEV–ZEL'DOVICH EFFECT IN THE SOUTH POLE TELESCOPE SURVEY

We report the first investigation of cool-core properties of galaxy clusters selected via their Sunyaev–Zel'dovich (SZ) effect. We use 13 galaxy clusters uniformly selected from 178 deg2 observed with the South Pole Telescope (SPT) and followed up by the Chandra X-ray Observatory. They form an approximately mass-limited sample (>3 × 1014 M☉ h−170) spanning redshifts 0.3 < z < 1.1. Using previously published X-ray-selected cluster samples, we compare two proxies of cool-core strength: surface brightness concentration (cSB) and cuspiness (α). We find that cSB is better constrained. We measure cSB for the SPT sample and find several new z > 0.5 cool-core clusters, including two strong cool cores. This rules out the hypothesis that there are no z > 0.5 clusters that qualify as strong cool cores at the 5. 4σ level. The fraction of strong cool-core clusters in the SPT sample in this redshift regime is between 7% and 56% (95% confidence). Although the SPT selection function is significantly different from the X-ray samples, the high-z cSB distribution for the SPT sample is statistically consistent with that of X-ray-selected samples at both low and high redshifts. The cool-core strength is inversely correlated with the offset between the brightest cluster galaxy and the X-ray centroid, providing evidence that the dynamical state affects the cool-core strength of the cluster. Larger SZ-selected samples will be crucial in understanding the evolution of cluster cool cores over cosmic time.
Detection of cell surface and intracellular antigens by human monoclonal antibodies. Hybrid cell lines derived from lymphocytes of patients with malignant melanoma

This study represents an initial attempt to analyze the humoral immune reactions of patients with malignant melanoma by hybridoma methodology. Using lymphocytes from regional lymph nodes, peripheral blood and tumor infiltrates, 158 fusions were performed with SKO-007 (human myeloma line), LICR-LON-HMy2 (LICR-2), GM 4672 (human lymphoblastoid lines), or NS-1 (mouse myeloma line). Fusion of lymph node lymphocytes with NS-1 resulted in a 3-4 times higher frequency of clones than fusion with LICR-2, and a 10 times higher frequency than fusion with SKO-007 or GM 4672. In the case of peripheral blood lymphocytes, fusion with NS-1 gave greater than 25 times higher frequency of clones than fusion with LICR-2 or SKO-007. Production of human mu, gamma, or alpha heavy chains was detected in 50-80% of wells containing growing clones, and the levels of immunoglobulin ranged from 0.3 micrograms to 40 micrograms/ml. NS-1-derived clones could be easily subcultured, while LICR-2 and SKO-007 clones grew more slowly on subculturing. In this study, Ig secretion appeared to be a more stable property of LICR-2- derived clones than NS-1-derived clones. A panel of 20 human cancer cell lines was used to screen 771 Ig-secreting cultures for antibody to cell surface or intracellular antigens. Reactivity with cell surface antigens was found infrequently (6 cultures), whereas reactivity with intracellular antigens was more common (27 cultures). A new cell surface antigen with properties of a glycolipid was defined with an IgM monoclonal antibody secreted by a tetraploid cell derived from a fusion of LICR-2 with lymphocytes from the axillary lymph node of a patient with melanoma. The hybrid cell line has been subcloned four times and secretes 5 micrograms IgM/ml. The antigen detected by this IgM antibody was found on 5 of 23 melanoma cell lines and 12 of 30 epithelial cancer cell lines. No reactions were found with 11 cultures derived from normal cells. Stable cell lines secreting human antibody that detected nuclei, nucleoli, cytoskeletal elements, Golgi complex, or other cytoplasmic components were also isolated in this study. One of these antibodies detected an intracellular antigen that is restricted to cells of neuroectodermal derivation, and a second antibody reacted primarily with cells of epithelial origin. Using these methods to isolate and analyze human monoclonal antibody, it should now be possible to define the repertoire of the humoral immune response to melanoma.
