Surface Urban Heat Islands Dynamics in Response to LULC and Vegetation across South Asia (2000-2019)

Urbanization is an increasing phenomenon around the world, causing many adverse effects in urban areas. Urban heat island is are of the most well-known phenomena. In the present study, surface urban heat islands (SUHI) were studied for seven megacities of the South Asian countries from 2000–2019. The urban thermal environment and relationship between land surface temperature (LST), land use landcover (LULC) and vegetation were examined. The connection was explored with remote-sensing indices such as urban thermal field variance (UTFVI), surface urban heat island intensity (SUHII) and normal difference vegetation index (NDVI). LULC maps are classified using a CART machine learning classifier, and an accuracy table was generated. The LULC change matrix shows that the vegetated areas of all the cities decreased with an increase in the urban areas during the 20 years. The average LST in the rural areas is increasing compared to the urban core, and the difference is in the range of 1–2 (°C). The SUHII linear trend is increasing in Delhi, Karachi, Kathmandu, and Thimphu, while decreasing in Colombo, Dhaka, and Kabul from 2000–2019. UTFVI has shown the poor ecological conditions in all urban buffers due to high LST and urban infrastructures. In addition, a strong negative correlation between LST and NDVI can be seen in a range of −0.1 to −0.6.

Biogas for a Distributed Development: Lessons learnt from Italian and Swedish cases

This thesis has two values. On one side, it aims at being a contribution to a betterunderstanding of the original concept of distributed economies. On the other side, it aspires atproviding useful decision criteria to those stakeholders that plan to locally develop a biogassystem.This thesis is developed from the Distributed Economies concept, which envisionsdecentralized, self-reliant and synergistically networked systems of production andconsumption, aiming at social well-being and quality of life. The study primarily focuses onenergy, and more specifically on systems dealing with biogas from anaerobic digestion. Itexplores how biogas can contribute to a distributed development of an area, and how theimplementation of such a system can be locally undertaken.The research first looks into three existing biogas systems, namely, Kristianstad and Vasterasin Sweden, and Camposampiero in Italy. Based on these cases, recommendations for anaudience-case, which is Umbertide, in the Centre of Italy, are elaborated.The findings underline the importance of a bottom-up and participative approach, meant tovalorize local resources and to grasp context-specific opportunities.Five factors enabling a distributed energy system have been identified, and they concernsupply, demand, technology, actors and financing.
Making it Personal in a Call Centre: Electronic Peer Surveillance

This paper analyses a form of electronic surveillance in a call centre that was not automatically performed through or by information and communication technology but required the active involvement of peers to provide feedback on each other's work by using an online reporting tool. Increased surveillance led to a tightening of control over certain aspects of work as advisors modified their call‐handling practices. But surveillance was simultaneously undermined by technical and bureaucratic control linked to existing information systems, which affected the ability and availability of peers to perform monitoring. Electronic peer surveillance was also unable to provide objective information or unobtrusive control as performing and evaluating surveillance became a highly political and contested process. Various forms of resistance arose, which were not always directed at management, but were instead manifest through increased animosity between teams.
Mechanisms for axial band formation in a rotating drum of granular material

Title of dissertation: MECHANISMS FOR AXIAL BAND FORMATION IN A ROTATING DRUM OF GRANULAR MATERIAL Michael K. Newey, Doctor of Philosophy, 2006 Dissertation directed by: Professor Wolfgang Losert Department of Physics We study granular particles, like sand or glass beads, that are mixed in a partially filled, horizontal, cylindrical drum. When the drum is rotated, it is observed that there is a flowing layer of grains on the free surface of the granular medium. In addition, if the particles have different sizes, spatial segregation of the particles by size is obsurved. This segregation occurs in two phases. During the first phase, called radial segregation, the smaller particles form a radial core. In the second, called axial segregation, particles segregate into alternating bands along the axis of the drum. We perform a detailed study of the characteristics of the flow to determine the physical mechanisms driving axial segregation. We characterize the top surface of the flowing layer by tracking particles using a high speed camera. We then extract average quantities such as velocity and diffusion. The average velocities show surprising behavior: Particles in small particle bands have a higher downhill flow velocity than particles in large particle bands. We also observe that there is a pattern of sideways velocity as a function of position down the flow. Particles flow into small particle bands in the middle of the flow but flow out of small particle bands at the bottom. We present the framework for a new model based on our experimentally observed results. We explain the axial band formation in terms of the observed surface flow patterns. We show how two physical processes could contribute to the band formation: A. ) Accelerating granular material does not necessarily collide while decelerating granular material requires collisions. B. ) Different size particles flow at different velocities. Our framework connects differences in flow velocities on the surface of the drum with the radial segregation in the bulk of the drum. We compare these results to current models, including models by Savage, Zik, Aranson, and Elperin. We test the general model assumption that the particles always flow in the direction of steepest descent by measuring the surface height of the banded state with a laser line. We find that although there is some indication that particles flow in the direction of steepest descent, there is strong flow that is not in the direction of steepest descent, contrary to the given models. Finally, we study oscillating patterns in mixtures of three sizes of glass beads. Ternary mixtures of particles form bands within bands of the different particle sizes. For certain experimental conditions we observe traveling and oscillating patterns. We analyze these patterns in light of the different models for granular band formation. MECHANISMS FOR AXIAL BAND FORMATION IN A ROTATING DRUM OF GRANULAR MATERIAL
Together but Apart: ICT and Productivity Growth in Israel

There is widespread agreement about the important role played by Information and Communication Technologies (ICTs) in the US productivity revival and in the evolving US-EU productivity gap. In Israel, the ICT sector grew very rapidly during the 1990s and became a hotbed of innovation and technological advance by worldwide standards. Yet, Israel's overall productivity growth remained sluggish, with traditional sectors both in manufacturing and services seemingly unable to benefit from the success of the ICT sector. The main goal of this paper is to shed light on these twin developments. We use newly constructed data on industry-level ICT investments between 1990 and 2003 and estimate production functions for manufacturing industries augmented to include ICT capital. We find a significant elasticity of value-added with respect to ICT capital, which increases considerably with the technological sophistication of the industry. We also find that ICT capital deepening is the most important factor contributing to value added growth in manufacturing during 1995-2000, before the burst of the dot.com bubble. Because most ICT capital is concentrated in high tech industries, growth in manufacturing has been mostly confined to the high-tech sector. Facilitating the adoption of ICT in traditional industries is therefore crucial to achieving economy-wide growth. The Israeli experience described here - although restricted to the manufacturing sector - provides a useful example of the benefits and limitations associated with a growth strategy centred on a local ICT producing sector, however successful it might be.
Sensorless speed control of salient rotor PM synchronous motor based on high frequency signal injection and Kalman filter

The paper presents an approach to sensorless speed control of a salient rotor permanent magnet synchronous motor, based on a high frequency signal injection scheme improved by the use of Kalman filtering. The rotor position estimation error signal is extracted from both the d- and q-axis components of the high frequency current in the estimated rotor position reference frame. Then it is processed by a Kalman filter which yields position and speed estimates, based on a parameter independent mechanical model. The problem of carrier recovery is addressed and a simple but effective solution is presented and analysed. Realistic simulations accounting for the inaccuracy of the digital implementation are presented and discussed.
The Impact of Single and Two-Officer Patrols on Catching Burglars in the Act

This study is concerned with determining the relative success of single and two-officer patrols in catching burglars red-handed. It is based on a six-month study of 'in progress' burglary, funded by the UK Home Office's Policing and Crime Reducing Unit, using questionnaire surveys of patrol officers, burglary site surveys and police records. Although two-officer patrols appeared to be better at catching burglars, this reflected burglary characteristics, their circumstances prior to responding, and the fact that many used rapid response, 'zulu' cars, as much as the intrinsic advantages of having two officers instead of a single officer. Two-officer patrols' speed advantage operated only at distances from the burglary scene from which few patrols managed to reach the scene first or catch many burglars.
An experimental-numerical analysis of plastic zones initiation around holes in shields made of steel C45 under tension

The paper presents the results of research on the plastic zones formation in thin (3.51 [mm]) shields made of steel C45 with holes of 4, 10 and 20 diameters. The authorship method of identifying plastic macro-strains utilizing optical interference phenomenon was used in the experiments. The basic idea of the method is summarized below as being: “The occurrence of plastic deformations in the active process of loading is testiﬁed by a loss of the interference fringes that were previously present or by a clear and rapid change in their character”. In the experiments, the values of the stress initiating the ﬁrst plastic deformation were determined. In order to explain the processes of plastic deformation appearance a detailed stress state analysis in the holes surrounding area was realized with the use of Finite Element Method. Comparison of experimental results with the results of FEM calculations indicates that there are signiﬁcant quantitative as well as qualitative diﬀerences. Namely stresses initiating plastic deformations clearly exceed the value of R eH , and plastic deformation are of local plastic slides character. Similar results were previously obtained in studies on the shields made of steel 15CrMo with holes.
Reliability of Parameter Values Estimated Using Trajectory Observations

Parameter values obtained by calibrating a car-following model using trajectory observations can provide important new insights into longitudinal driving behavior that cannot be derived from double loop detector data. However, that holds only if these behavioral parameters can be reliably estimated. This important aspect of calibration has been generally neglected in scientific research. In this contribution, therefore, calibrations are done to analyze several aspects influencing the degree to which behavioral parameters can be reliably estimated. In these calibrations trajectory data created by the authors with known characteristics as well as empirical trajectories are used. It is shown that traffic conditions during observation determine which model parameters can be reliably estimated. That measurement errors do negatively influence the reliability of parameter estimates is also demonstrated. The same negative effect appears to occur when a car-following model not fully able to capture the dynamics of the observed driver is calibrated. Finally, it is found that the extent to which a specific parameter can be reliably estimated is dependent on the degree to which it affects model predictions and thereby the value of the calibration objective. From this contribution it is concluded that to answer a specific research question on longitudinal driving behavior, it is essential to collect trajectories during appropriate traffic conditions. The results furthermore stress that even when trajectories contain enough information to calibrate the behavioral parameters of interest, whether it is reliable enough to draw inferences on car-following behavior needs to be determined for every parameter value separately.

Seroprevalence of hepatitis E virus infection in acute leukemia patients with allogeneic transplantation

Aim: Hepatitis E Virus (HEV) infection is an emerging threat in allogeneic Hematopoietic Stem Cell Transplant (allo-HSCT) recipients. The aim of this study was to determine the prevalence of HEV infection in patients with acute leukemia before and after the transplantation. Material and Methods: The study was carried out with the serum samples taken before and after the transplantation from patients (n=42) with acute leukemia, who were 4 months to 64 years of age and who had allogenic transplant at Gazi University Hospital. All samples were tested in terms of HEV-specific anti-IgG and IgM positive value by using ELISA kit. Results: While 1 (2.3%) of the samples that were included in the study was positive anti-HEV IgG before transplantation, it was found negative after the transplantation (58th month). Positive anti-HEV IgM was not found before and after the transplantation in the collected samples. The average age of the seronegative group was determined as 30.8 ± 33.1 for male and female, respectively. There was no statistically significant difference in terms of anti-HEV IgM positivity and anti-HEV IgG positivity compared with seronegative cases of seropositive cases. Conclusions: This study was conducted to determine the prevalence of HEV infection in allogeneic stem cell patients. With this study, the incidence and importance of HEV can be determined in these patients before and after transplantation. This study can also create an important epidemiological data for our country .
Kinetic model of excitation of pairing vibrations in superfluid nuclei

Excitation of pairing vibrations in superfluid nuclei is studied by using a kinetic model based on the Vlasov equation with pairing, derived from the time-dependent Hartree-Fock-Bogolyubov theory. The anomalous density response function is used to find the monopole pairing mode and the dynamic variation of the pairing gap associated with this mode. The spectroscopic factor for the excitation of monopole pairing vibrations in two-neutron transfer reaction is estimated. It is found that the pairing correlations give rise to the same coherent contribution to the semiclassical spectroscopic factor as to the corresponding quantum expression, which is essentially determined by the distribution of the neutron levels near the Fermi energy. A numerical evaluation of the reduced spectroscopic factor for the excitation of monopole pairing vibrations in two-neutron transfer reaction in superfluid nuclei shows that it does not exceed several percent of the spectroscopic factor for the transfer of two neutrons to the ground state. This estimate is in agreement with the experimental data obtained for the ratio of the cross section for the excitation of 0+state in the (p,t) reaction in the energy region of double pairing gap to the cross section for the excitation of the ground state for superfluid nuclei of the rare-earth and actinide regions.
Analog-digital systems for adaptive measurements and parameter estimation of noisy processes

The theoretical framework and principles of designing a new class of highly effective analog-digital computer-aided measurement systems are presented. The proposed approach enables the designers to determine uniquely the optimal structure, parameters and characteristics of measurement systems working in the presence of noises and disturbances as well as to carry out the comprehensive analysis of their work. The approach is based on the new idea of the nonlinear adaptively controlled (smart) sensor. The algorithms for optimal processing of the measured data and estimating unknown parameters of analyzed processes or objects, coupled with the optimal adaptive control of the sensor parameters, are derived. The superiority of measurement systems with adaptively controlled sensors over the conventional ones employing nonadaptive sensors is shown. The main theoretical results and conclusions are verified and confirmed via simulations taking as an example the string-frame accelerometer.
