MULTI-SPATIOTEMPORAL PATTERNS OF RESIDENTIAL BURGLARY CRIMES IN CHICAGO : 2006-2016

This research attempts to explore the patterns of burglary crimes at multi-spatiotemporal scales in Chicago between 2006 and 2016. Two spatial scales are investigated that are census block and police beat area. At each spatial scale, three temporal scales are integrated to make spatiotemporal slices: hourly scale with two-hour time step from 12:00am to the end of the day; daily scale with one-day step from Sunday to Saturday within a week; monthly scale with one-month step from January to December. A total of six types of spatiotemporal slices will be created as the base for the analysis. Burglary crimes are spatiotemporally aggregated to spatiotemporal slices based on where and when they occurred. For each type of spatiotemporal slices with burglary occurrences integrated, spatiotemporal neighborhood will be defined and managed in a spatiotemporal matrix. Hot-spot analysis will identify spatiotemporal clusters of each type of spatiotemporal slices. Spatiotemporal trend analysis is conducted to indicate how the clusters shift in space and time. The analysis results will provide helpful information for better target policing and crime prevention policy such as police patrol scheduling regarding times and places covered.
CALIBRATION OF THE SR 4500 TIME-OF-FLIGHT CAMERA FOR OUTDOOR MOBILE SURVEYING APPLICATIONS : A CASE STUDY

3D-cameras based on Time-of-Flight (ToF) technology have recently raised up to a commercial level of development. In this contribution, we investigate the outdoor calibration and measurement capabilities of the SR4500 ToF camera. The proposed calibration method combines up-to-date techniques with robust estimation. First, intrinsic camera parameters are estimated, which allows converting radial distances into orthogonal ones. The latter are then calibrated using successive acquisitions of a plane at different camera positions, measured by tacheometric techniques. This distance calibration step estimates two coefficient matrices for each pixel, using linear regression. Experimental assessments carried out with a 3D laser-cloud after converting all the data in a common basis show that the obtained precision is twice better than with the constructor default calibration, with a full-frame accuracy of about 4 cm. Moreover, estimating the internal calibration in sunny and warm outdoor conditions yields almost the same coefficients as indoors. Finally, a test shows the feasibility of dynamic outdoor acquisitions and measurements.
Application of System Engineering in Election Voting System

Election System is one of the indicators of the democratic country when this country is giving equal rights to the eligible citizens to choose their leaders or to give their candidatures, to participate in the country development by criticizing the government on how thing are being done and how they want to be done (i.e. means listen the views of the citizens). An E-voting system is one of the system engineering where different technologies are applied to analyze, design and implement a dynamic system which is satisfying the user needs. In this work we are discussing on the futures of Election Management System (EMS) by mentioning some of the problems and coming up with the solutions. The system is having the strong securities in the way that the hackers cannot be able to enter our system to make any change during the registration of the voters and candidates as well as in the election period till the end of election (i.e. tabulation, store votes, and display the final election results). We are developing, designing and implementing Electronic Voting Machine composed by Hardware, Software and Network.
Key Regulators of Sucrose Accumulation during Different Developmental Phases of Sugar Beet Plants

BECAUSE of the economic importance of sugar beet (Beta vulgaris L) in sucrose production, a field experiment was conducted to elucidate the key regulators of sucrose metabolism in source leaves and sink roots at 135, 150, 165 and 180 day after sowing (DAS) that would be determined sucrose yield. Increase in sucrose phosphate synthase (SPS) activity in source and sink tissues during the first three selected harvest phases was associated in leaves with an increase in activities of acid invertase (AI) and neutral invertase (NI), chlorophyll a, total chlorophyll and reducing sugars on the one hand and the levels of sucrose and inorganic phosphorus (Pi) in roots on the other hand. The maximum sucrose level in roots was at 165 DAS. A gradual increase in root NI activity accompanied by an increase in reducing sugars and a decrease in the sucrose/reducing sugars ratio in roots by harvest date progress was observed. Pearson correlation test revealed contradictory findings whereas, SPS activity correlated with sucrose level in leaves negatively but positively in roots. All investigated enzymes in leaves correlated negatively with sucrose/reducing ratio. But in roots, only NI activity correlated negatively with sucrose/reducing sugars ratio.
0 Sensor Fusion for Enhancement in Intrusion Detection

An Intrusion Detection System (IDS) gathers information from a computer or a network, and analyzes this information to identify possible security breaches against the system or the network. An observation of various IDSs available in literature shows distinct preferences for detecting a certain class of attack with improved accuracy, while performing moderately on the other classes. The availability of enormous computing power has made it possible for developing and implementing IDSs of different types on the same network. The integration of the decisions coming from different IDSs has emerged as a technique that could strengthen the final decision. Sensor fusion can be defined as the process of collecting information from multiple and possibly heterogeneous sources and combining them to obtain a more descriptive, intuitive and meaningful result (1). An analysis of the poorly detected attacks reveals the fact that the attacks are characterized by features that do not discriminate them much. In this chapter, we prove the distinct advantages of sensor fusion over individual IDSs. All the related work in the field of sensor fusion has been carried out mainly with one of the methods like probability theory, evidence theory, voting fusion theory, fuzzy logic theory or neural network in order to aggregate information. The Bayesian theory is the classical method for statistical inference problems. The fusion rule is expressed for a system of independent learners, with the distribution of hypotheses known a priori. The Dempster-Shafer evidence theory is considered a generalized Bayesian theory. It does not require a priori knowledge or probability distribution on the possible system states like the Bayesian approach and it is mostly useful when modeling of the system is difficult or impossible (2). The improved performance of multiple IDSs using rule-based fusion and deta-dependent decision fusion has been demonstrated in the work of Thomas and Balakrishnan (3). An attempt to prove the distinct advantages of sensor fusion over individual IDSs is done in this chapter using the Chebyshev inequality. Fusion threshold bounds were derived using the principle of Chebyshev inequality at the fusion center using the false positive rates and detection rates of the IDSs. The goal was to achieve best fusion performance with the least amount of model knowledge, in a computationally inexpensive way. The anomaly-based IDSs detect anomalies beyond a set threshold level in the features it detects. Threshold bounds instead of a single threshold give more freedom in steering system properties.

Open Source Tool for Networks Management Communication

Considering the complexity of the networks and the need for telecommunication operators (Telco) to present innovations to their clients, the quickest possible, one of the solutions for this complexity could be to centralize its configuration. Thus the SDN (software-defined networking) concept may be an important solution. This paper suggests the implementation of a tool to support the development and testing of networks and services before they are put into production. The use of a tool that simplifies the configuration of a network service makes the networks and services to be less susceptible to errors and failures by those who set them up, thus allowing telecom operators, among others, to be able to create new services, improve the monitorization of their human resources and, above all, improve their financial results. In the end, success will be achieved because with a simple interaction and basic knowledge we are able to manage network services.
Issues in Teachers´ Reinterpretation of a Task- Based Innovation in Primary Schools.

Although task-based teaching is frequently practiced in contemporary English language teaching, it is underresearched in state school settings. This article contributes to filling this gap in the literature by using qualitative case study data to explore how a task-based innovation was implemented in three primary school classrooms in Hong Kong. Analysis of classroom observation and interview data shows how the case study teachers reinterpreted a new curriculum in line with their own beliefs and the practical challenges occurring in their school contexts. Drawing on classroom episodes, the article highlights three issues that proved problematic when the tasks were implemented: use of the mother tongue, classroom management or discipline problems, and the quantity of target language produced. Implications for the design and implementation of task-based pedagogies in primary school contexts are discussed.
PERFORMANCE ANALYSIS OF ZERO CROSS- CORRELATION CODE IN SAC-OCDMA WITH DCF AND EDFA

Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) is a future communication technique because of its high speed, efficiency, security and unlimited bandwidth capability. There are many codes used to make it more scalable, flexible, reduce Multiple Access Interface (MAI). But the minimum crosscorrelation property is the code’s best property. So Zero Cross Correlation (ZCC) code used in SAC-OCDMA with zero cross correlation property enhance the system performance. In this paper the performance of ZCC code in SAC-OCDMA system without EDFA, with EDFA, with DCF and both EDFA and DCF is analysed for 5 numbers of users at data rate of 10 Gbps. The simulation result analysed in optisystem 7.0.
Single reference mobile localisation in multipath environment

A wireless localisation scheme which requires just one reference device to estimate the mobile location is presented. The proposed scheme utilises the joint time-of-arrival and angle-of-arrival estimation of the line-of-sight path measured at both mobile and reference devices to construct areas of possible mobile devices (APMDs). The intersection of these APMDs will give an estimation of an MD location. Simulations in light and heavy multipath environments show that the performance of the proposed single reference localisation scheme dramatically improved the location accuracy as compared with the conventional localisation techniques that use four reference devices.
Patterns of summer rainfall variability across tropical Australia - results from EOT analysis

EOT analysis provides for relatively simple, easily interpretable results when applied to rainfall data. Previous studies have applied this technique to Australian average annual rainfall data and identified dominant modes of variability, including long term trends. Here we use EOT analysis to identify modes of summer (November to April) average rainfall variability with a focus on recent decades. The dominant mode is centered over the Northern Territory but also encompasses much of the continent and represents a trend towards wetter conditions. The fourth mode is centered over Western Australia and although it also represents a significant trend towards wetter conditions, it is also linked to a drying trend over the eastern half of the continent. These trends are not related to changes in ENSO, but appear linked to a global pattern of changes in the hydrological cycle. Furthermore, even though these changes are not well simulated by existing climate models, the observed rainfall trends have occurred while global average temperatures have increased. Consequently, they may provide a more accurate indication of changes to be expected for this century if global warming continues.
Structural dynamic analysis for time response of bars and trusses using the generalized finite element method

The Generalized Finite Element Method (GFEM) can be viewed as an extension of the Finite Element Method (FEM) where the approximation space is enriched by shape functions appropriately chosen. Many applications of the GFEM can be found in literature, mostly when some information about the solution is known a priori. This paper presents the application of the GFEM to the problem of structural dynamic analysis of bars subject to axial displacements and trusses for the evaluation of the time response of the structure. Since the analytical solution of this problem is composed, in most cases, of a trigonometric series, the enrichment used in this paper is based on sine and cosine functions. Modal Superposition and the Newmark Method are used for the time integration procedure. Five examples are studied and the analytical solution is presented for two of them. The results are compared to the ones obtained with the FEM using linear elements and a Hierarchical Finite Element Method (HFEM) using higher order elements.
Antibacterial potential of methanolic and hexanic extracts of mud lobster (Thalassina anomala) from Bintulu, Sarawak, Malaysia

Present study demonstrated the antibacterial potential of three different body parts, abdomen, carapace and cheliped of mud lobster (Thalassina anomala) which were extracted with methanol and hexane. Three test bacteria were used in this study namely Bacillus cereus, Escherichia coli, and Salmonella enterica. Present study found that in general, methanolic and hexane extracts of different body parts had variable inhibitory responses on different test bacteria with methanolic extract had greater inhibitory response than hexane extract. In methanol extraction, B. cereus significantly had greatest negative impact (p<0.05) on growth after treated with cheliped (21 mm zone of inhibition) extract of mud lobster as compared to carapace (9.2 mm) and abdominal (8.8 mm) extracts of mud lobster. Overall, the growth of S. enterica was much affected with the presence of all methanolic body-part extracts of mud lobster. In hexane extraction, B. cereus growth was not affected with all body-part extracts of mud lobster. However, E. coli and S. enterica were affected with no significantly different (p>0.05) among body-part extracts and between them. Present study concludes that the extracts of mud lobster of all body-part in methanol possess greater inhibitory effect on bacterial growth than extracts in hexane thus the methanolic extract of mud lobster has the potential to be exploited as a natural source of antibacterial agent.
MODELING THE POWER ALLOCATION IN DYNAMIC SPECTRUM ACCESS FOR COGNITIVE RADIOS AS A GENERALIZED NASH EQUILIBRIUM PROBLEM

The demand of radio resources like mobile phones and Internet services is dramatically increasing and inefficiency in the traditional allocation of electromag- netic spectrum is apparent. A novel paradigm for allocating resources is the Dynamic Spectrum Access, where primary and secondary users share the same frequency band. In this paper, in a Cognitive Radio context, we model the power allocation for secondary users coexisting in the same frequency band with primary ones as a Gener- alized Nash Equilibrium Problem. We develop a theoretic analysis showing existence and uniqueness of the Generalized Nash Equilibrium and convergence of the Best Re- sponse Algorithm to it. In practical implementations, the conditions we propose are natural (a lower and an upper bound for the Signal-to-Interference-plus-Noise-Ratio of the radio devices are involved) and easy to be locally verified by users, which just need the knowledge of the total interference they experience near their own receiver.
A Semantical Interpretation of the Post-Electoral Newspaper Reporting in Gaining the Legitimacy from the Citizens: A Case Study of the Newspaper Articles Headlines during the Post-Electoral Period

This qualitative study focuses on the semantical interpretation of the post-electoral newspaper reporting in gaining the legitimacy from the citizens. The study is being addressed through two research questions: 1) what are the semantical interpretation of the newspaper articles’ headlines in the mainstream and the oppositions’ newspapers? 2) What are the issues highlighted in the newspaper during the post-electoral period of the 13th General Election? The data for the entire research were obtained through the mainstream newspapers which are Utusan Malaysia, Kosmo and Harian Metro and also the opposition’s newspaper represented by Harakah. The data were also collected based on the newspapers that were published after the Election Day has ended. However, the newspapers were not collected daily as the researcher has chosen a few newspapers that contained the traits of having portrayed electoral campaign. The data were analysed using the thematic analysis by deriving themes from the content analysis of the newspapers. The findings were divided into two sections which are semantical interpretations of newspaper articles’ headlines during post-electoral period and issues highlighted in the political campaigns. The researcher has come to a conclusion that both mainstream and opposition based newspapers were portraying improper political headlines during the post-electoral period.
EXPERIMENT AND NUMERICAL SIMULATION RESULTS OF PLASMA WINDOW

Plasma window is one of the windowless vacuum sealing techniques which can isolate high vacuum cavity from low vacuum or atmosphere device by plasma. A test bench was constructed in the past two years. In this paper, preliminary experimental results are presented and discussed. A numerical 2D FLUENT-based magnetohydrodynamic model has been developed to investigate the sealing mechanism of plasma pressure difference distributed in plasma channel. The simulation results are consistent with the experiment results.
INVESTORS’ TRADING AND RELATIVE PERFORMANCE OF ANALYSTS DURING THE CRISIS PERIOD

This paper documents the relationship between foreign and local analysts’ recommendations and subsequent trades done by different investor groups – foreign investors, local institutional investors, and local individual investors. Using analysts’ recommendations and investors’ trading data from South Korea, we show that foreign analysts’ buy recommendations and local analysts’ sell recommendations generate significantly more subsequent trade than their respective counterpart recommendations (i.e. local analysts’ buy and foreign analysts’ sell recommendations) during the Asian financial crisis of 1997-98. We argue that the ability of foreign analysts’ buy recommendations and local analysts’ sell recommendations to generate trade is responsible for superior performance foreign analysts’ buy recommendations and local analysts’ sell recommendations in emerging stock markets. We also show that earlier explanations proposed to explain the asymmetric performance of foreign and local analysts’ recommendations do not hold in our sample period.
How Good is Employee Welfare in Indian PSUs? Some Empirical Evidence

Best employee welfare practices help an organization achieve competitive advantage as they keep morale of the employees at a higher point and thereby ensure high degree of employee commitment towards its goals. The present study compared various welfare practices between the two selected PSUs i.e. RINL and BHEL and identified similarities as well as differences in their operations. For example, BHEL is significantly doing better than RINL with regard to welfare activities viz. staff benevolent fund, pension scheme, quality of canteen food, restrooms, medical benefits, cooperative credit society and ambulance and medical services. However, regarding recreation facilities, educational allowance, workplace safety, canteen subsidy, canteen hygiene, workplace hygiene, medical facilities, family welfare, housing facilities, etc. more or less similar conditions exist in both the organisations investigated. This study suggests benchmarking of welfare practices between Maharatna and Navaratna PSEs to achieve welfare excellence and to promote harmonious industrial relations in the industry.
How far are the platelet indices mirror image of mechanism of thrombocytopenia-mystery still remains.

Background: Evaluation of thrombocytopenia requires thorough clinical history, examination, complete hemogram, including platelet indices and bone marrow study whenever indicated. The etiopathogenetic mechanism decides patient management. The aim was to study relationship between thrombocytopenia and platelet indices with respect to underlying mechanisms. Methods: Totally 100 thrombocytopenic patients with sufficient clinico-hematological workup were included in our study. Results were confirmed by peripheral smear examination and manual platelet count wherever necessary. Similar data during the year 2012 were collected from 100 controls and compared. Results: Patients were grouped based on mechanism-hypoproduction 15 (megaloblastic anemia 8, myelodysplastic syndrome 1, leukemia 6), hyperdestruction 4 (immune thrombocytopenic purpura), hyperspleenism 19 (chronic dengue 10, chronic malaria 6, chronic liver disease 3) and mixed 62 (chronic dengue 29, chronic malaria 24, thalassemia on regular transfusion 3, sepsis 4, disseminated intravascular coagulopathy 2). Conclusion: (1) Platelet indices showed inverse relationship-increase (mean platelet volume [MPV] r = −0.805, platelet distribution width [PDW] r = –0.996) with decreasing platelet count in most increased destruction cases, (2) linear relationship (MPV r = 0.84, PDW r = 0.37) was seen in most hypoproduction cases. p values were also calculated, (3) variable results were obtained in hyperspleenism, mixed and few of above two groups, (4) platelet indices provide important information about platelet kinetics. However, relationship with platelet count is helpful but not always confirmative of mechanism of thrombocytopenias.
Calibration approaches of cosmic-ray neutron sensing for soil moisture measurement in cropped fields

Abstract. Measurement of soil moisture at the plot or hill-slope scale is an important link between local vadose-zone hydrology and catchment hydrology. This study evaluates the applicability of the cosmic-ray neutron sensing for soil moisture in cropped fields. Measurements of cosmic-ray neutrons (fast neutrons) were performed at a lowland farmland in Bornim (Brandenburg, Germany) cropped with sunflower and winter rye. Three field calibration approaches and four different ways of integration the soil moisture profile to an integral value for cosmic-ray neutron sensing were evaluated in this study. The cosmic-ray sensing (CRS) probe was calibrated against a network of classical point-scale soil moisture measurements. A large CRS parameter variability was observed by choosing calibration periods within the different growing stages of sunflower and winter rye. Therefore, it was not possible to identify a single set of parameters perfectly estimating soil moisture for both sunflower and winter rye periods. On the other hand, CRS signal and its parameter variability could be understood by some crop characteristics and by predicting the attenuated neutrons by crop presence. This study proves the potentiality of the cosmic-ray neutron sensing at the field scale; however, its calibration needs to be adapted for seasonal vegetation in cropped fields.
