CONVERGING REDUNDANT SENSOR NETWORK INFORMATION FOR IMPROVED BUILDING CONTROL

Knowing how many people occupy a building, and where they are located, is a key component of building energy management and security. Commercial, industrial and residential buildings often incorporate systems used to determine occupancy, however, current sensor technology and control algorithms limit the effectiveness of both energy management and security systems. This topical report describes results from the first phase of a project to design, implement, validate, and prototype new technologies to monitor occupancy, control indoor environment services, and promote security in buildings. Phase I of the project focused on instrumentation and data collection. In this project phase a new occupancy detection system was developed, commissioned and installed in a sample of private offices and open-plan office workstations. Data acquisition systems were developed and deployed to collect data on space occupancy profiles. Analysis tools based on Bayesian probability theory were applied to the occupancy data generated by the sensor network. The inference of primary importance is a probability distribution over the number of occupants and their locations in a building, given past and present sensor measurements. Inferences were computed for occupancy and its temporal persistence in individual offices as well as the persistence of sensor status. The raw sensor data were also used to calibrate the sensor belief network, including the occupancy transition matrix used in the Markov model, sensor sensitivity, and sensor failure models. This study shows that the belief network framework can be applied to the analysis of data streams from sensor networks, offering significant benefits to building operation compared to current practice.
Turnover in Life-Strategies Recapitulates Marine Microbial Succession Colonizing Model Particles

Particulate organic matter (POM) in the ocean sustains diverse communities of bacteria that mediate the remineralization of organic complex matter. However, the variability of these particles and of the environmental conditions surrounding them present a challenge to the study of the ecological processes shaping particle-associated communities and their function. In this work, we utilise data from experiments in which coastal water communities were grown on synthetic particles to ask which are the most important ecological drivers of their assembly and associated traits. Combining 16S rRNA amplicon sequencing with shotgun metagenomics, together with an analysis of the full genomes of a subset of isolated strains, we were able to identify two-to-three distinct community classes, corresponding to early vs. late colonizers. We show that these classes are shaped by environmental selection (early colonizers) and facilitation (late colonizers), and find distinctive traits associated with each class. While early colonizers have a larger proportion of genes related to uptake of nutrients, motility and environmental sensing with few pathways enriched for metabolism, late colonizers devote a higher proportion of genes for metabolism, comprising a wide array of different pathways including metabolism of carbohydrates, amino acids and xenobiotics We find evidence in selected metabolic pathways for the existence of a trophic-chain topology connecting both classes. The interpretation of these traits suggests a distinction between early and late colonizers analogous to other classifications found in the literature, and we discuss connections with the classical distinction between r- and K-strategists.
Expression of Anaplastic Lymphoma Kinase in Astrocytic Tumors (Histopathological and Immunohistochemical Study)

BACKGROUND: Astrocytic tumors are the most common primary brain tumors. Glioblastoma is the most common astrocytic tumor representing the highest World Health Organization (WHO) grade (WHO grade IV) with poor prognosis and short survival time. Anaplastic lymphoma kinase (ALK) has a role in embryonic central nervous system development. ALK receptor is thought to contribute to nervous system function, repair, and metabolic homeostasis and is expressed in high-grade tumors like anaplastic large cell lymphoma that makes it a potential target for therapeutic intervention. AIM: This work aimed to examine the immunohistochemical expression of ALK in astrocytic tumors and its correlation with age, sex, clinical presentation, location, laterality, recurrence, and WHO grade to implicate possible therapeutic potential. METHODS: This retrospective study was conducted on sixty cases of archived, formalin-fixed, paraffin-embedded tissue blocks that included different subtypes and grades of astrocytic tumors. Immunohistochemistry using ALK monoclonal antibody was performed using a standard avidin-biotin-peroxidase system. RESULTS: Of the sixty cases, 57 (95%) cases were negative for ALK, while three (5%) cases are positive for ALK; all showed the strong intensity of expression. No statistically significant association was found between ALK expression and astrocytic tumors in addition to other clinical variables of the studied tumors. CONCLUSIONS: Most cases of astrocytic tumors showed negative ALK expression apart from three positive cases seen in higher WHO grades, especially gliosarcoma. The high number of negative cases for ALK in our study group suggests that ALK expression is not associated with a prognostic significance toward astrocytic tumors whatever its grade.

DOES OIL DEPENDENCE AFFECT REGIONAL WEALTH? A REGIONAL STUDY FOR THE MUNICIPALITIES OF THE STATE OF RIO DE JANEIRO

The aim of this study is to analyze the regional effects of oil royalty dependence on the local economic development of municipalities of the Rio de Janeiro state. To do so, we used spatial econometric models to estimate the local and spillover effects of royalty dependence on the economic local product. The main results were derived based on the Spatial Autoregressive Combined model (SAC) estimated by Generalized Moments (GM). The study’s contribution is to address the natural resource curse debate through its regional perspective by estimating the direct, spillover, and total effects of oil royalty dependence on economic product, which is a groundbreaking approach for the natural resource curse debate. The results show that both the direct and spillover effects are negative and significant, indicating that there is evidence of the presence of a regional natural resource curse in the municipalities of the Rio de Janeiro state.

The Role of Household Wealth in Combining Child School and Child Labor: Evidence from MICS Balochistan (Pakistan)

The issue of combining school & work has taken considerable focus in the past years from policymakers, advocates and researchers. In the literature, the role of household wealth, combining school & work is still an unresolved issue. The researchers have contradicting views about the impact of household wealth on combining child school & work. Child labor and low schooling attendance are found pervasive issues worldwide, particularly in developing countries. This study aims to explore the impact of household wealth on combining child school & work, particularly focusing on the wealth index of the household. For this purpose, microdata having 18471 observations from Multiple Indicator Cluster Survey Balochistan (2010) has been utilized. The binary logistic model has been applied for the children (5-15 years) activity whether they are combining school & work or not. The main finding of this paper is the wealth status of households which has a statistically significant and positive influence on combining child school & work. Both mother and father's education is positively associated with combining school & work. In addition, mother and father being alive played a vital role in their children’s combined activities of schooling & work rather than doing nothing because the expectations of child schooling are high in parent's lives. Furthermore, gender, age of the child, and area of residence are positive effects combining school & work. The children from urban zones are more likely to be involved in combining school & work. The policy of this paper suggests that education is the key to break child labor in society by providing education facilities for both girls and boys equally. In addition to policy recommendations, there should be crucial steps to provide a better economic environment for the well-being of the masses to enhance their economic condition especially in rural and deprived areas of Balochistan, and the applicability of child labor laws needs to be focused on.Keywords:
Leadership and Innovation - How Can Leaders Create Innovation-Promoting Environments in Their Organisations?

Abstract Innovation is considered to be among the most relevant success factors for companies in the contemporary business environment. Thus, finding strategies and approaches to foster innovation becomes a crucial challenge for managers and leaders alike. The present paper aims to showcase, how the working environment shaped by the present Covid-19 crisis with its enforced work-from-home-setting influences innovation processes. Therefore, an extensive literature review is conducted, where in a first step the challenges of leadership within a telework-environment are established. The author therein explains the differences between classic approaches towards this mode of virtual collaboration and the pandemic-induced, often mandatory approach to telework utilized throughout the pandemic. This leads to a description of how – especially in times of the Covid-19 pandemic – innovation becomes even more crucial for organizations not only in the medical field, as they need to react to a changing environment and, accordingly, changing customer needs. Leadership challenges of finding ways to create and shape innovation-friendly work environments and organizational cultures given the limitations of the situation, are presented and critically discussed.
Recurrent embodied energy and its relationship with service life and life cycle energy

Purpose – The recurrent embodied energy (REE) is the energy consumed in the maintenance, replacement and retrofit processes of a facility. The purpose of this paper was to analyze the relationship of REE with the service life and life cycle embodied energy. The amount of variation in the reported REE values is also determined and discussed. Design/methodology/approach – A qualitative approach that is known as the literature based discovery (LBD) was adopted. Existing literature was surveyed to gather case studies and to analyze the reported values of REE. Findings – The reported values of REE showed considerable variation across referred studies. It was also found that the reported REE values demonstrated a moderate positive correlation with the service life but a very strong positive correlation with the life cycle embodied energy of both the residential and commercial facilities. Research limitations/implications – This review paper pointed out the importance of the maintenance and replacement processes.
Openness to experience and overexcitabilities in a sample of highly gifted middle school students

A sample of 108 highly gifted middle school students participated in a study of the relationships between Big Five factors and overexcitabilities. Students completed the NEO-FFI and Overexcitabilities Questionnaire-II (OEQ-II). A cutoff score applied to the OEQ-II created a threshold for overexcitability, ensuring only extreme responses. Analysis groups were based on the number of OEs students possessed based on the cutoff score. An analysis of variance assessed differences in students’ NEO-FFI scores according to the number of OEs they reported. Students with three or more overexcitabilities had significantly higher scores on NEO-FFI openness to experience than students with fewer overexcitabilities. Gifted females had significantly higher scores on NEO-FFI neuroticism scale than gifted males. The results hold implications for understanding the academic and social-emotional needs of highly gifted students and justify use of the Big Five model and overexcitabilities together to further understand the relationship between intelligence, personality, and giftedness.
Monetary Policy in Sub-Saharan Africa: Lessons from a Dynamic Stochastic General Equilibrium Model Applied to Mozambique

Macroeconomic conditions in a number of sub-Saharan African countries have improved markedly in the past decade (IMF, 2005a), providing greater scope for stabilization policies. Higher economic growth rates have been associated with lower inflation rates, healthier public finances, and higher international reserves in a group of countries dubbed “mature stabilizers” (Selassie and others, 2006) or post-stabilization economies. Mozambique is one of these countries. In general, the central banks of the mature stabilizers are no longer subsumed by the fiscal authorities’ financing needs, a situation sometimes referred to as “fiscal dominance” (see Chapter 4). The possibility of an activist monetary policy provides the authorities with an important mechanism that can help them in their efforts to achieve economic stability.1 Political economy arguments provide little scope for the use of discretionary fiscal policy for stabilization in low-income countries because
Effect of feeding high yielding fodders on growth performance of growing Hilly Brown Bengal goat

This study was carried out to evaluate the feeding effect of high yielding fodders (HYF) on feed intake and growth performance of growing Hilly Brown Bengal (HBB) goat. For this purpose, a feeding trail was conducted with 16 growing HBB kids (4 to 5 months) by dividing equally in four groups having four replicates for a period of 75 days. The goats in group T0 (control) received natural grass along with 101.30g concentrates and adlibitum cowpea hay, whereas in group T1, T2 and T3, only natural grass was replaced by BLRI Napier 3, BLRI Napier 4 and Ruzi fodder, respectively. Total dry matter intake (DMI), roughages DMI, crude protein intake (CP), body weight gain (kg), average daily gain (g) and forth night body weight gain (g/day) were studied. Results revealed that, DMI (288.39, 285.71, 293.48 and 301.35 g/day in group T0, T1, T2 and T3, respectively), body weight gain (3.60, 3.74, 3.73 and 3.77 kg in group T0, T1, T2 and T3, respectively), average daily gain (47.32, 49.16, 49.12 and 48.92 g in group T0, T1, T2 and T3, respectively) and feed conversion ratio (6.2, 5.9, 6.0 and 6.1 in group T0, T1, T2 and T3, respectively) of HBB kids were not differed significantly (P>0.05) for all the treatment groups. The DMI from roughages (196.2, 193.5, 201.3 and 209.2 g/day in group T0, T1, T2 and T3, respectively) and CP intake (38.7, 42.1, 48.3 and 38.8 g/day in group T0, T1, T2 and T3, respectively) were significantly varied (P<0.05), while highest CP intake was found in the treatment group T2. Forthnight body weight (g/day) was not significantly (P>0.05) gained with feeding of HYF for all the treatment groups. From this study, it can be concluded that, growing HBB kids could equally be supplied with either BLRI Napier 3 or BLRI Napier 4 or Ruzi fodder in addition to ad libitum cowpea hay for better voluntary feed intake and growth.

Motion at low Reynolds number

Two rather different cases of motion at low Reynolds number are presented here. One is related to biolocomotion, the other to free surface flows. We will first examine the swimming properties of micro-organisms. Most living organisms exist at micrometric scales and many of them are able to propel themselves by beating flagella in a variety of different patterns. This study focuses on optimal flagellar swimming motions at low Reynolds number. We seek to optimize both the geometry of the swimmer and the kinematics of the flagellar beat pattern. This study first focuses on the optimal swimming of Purcell's simple three link swimmer. A number of more complex configurations will also be investigated including uniflagellate and biflagellate organisms. Next, we will look at the convective flow inside a small droplet of water sitting on top of a heated super-hydrophobic surface. Water is observed to be driven upwards on the surface of the spherical droplet and to accelerate downwards inside the droplet towards the contact point with the substrate. The driving mechanism of these convective rolls is investigated experimentally and numerically.

Thermal Diagnostics in the LISA Technology Package Experiment

LISA Pathfinder (LPF) is an ESA mission, with NASA contributions, devoted to pave the way to the future spaceborne gravitational wave observatory LISA.The LISA Technology Package (LTP) experiment in the LPF mission will measure the differential acceleration between two free falling test masses to the picometer resolution by using both masses as end mirrors of an interferometer, together with an active control loop, known as drag-free, that will act to keep the spacecraft centred around the geodesic motion of the masses. The work in this thesis deals with the thermal diagnostic subsystem, intended to measure and characterise the thermal noise contribution to the instrument performance: from the qualification of the high stability electronics designed to measure temperature fluctuations in the millihertz bandwidth to the definition of heaters, aimed to generate controlled perturbations during mission operations. The results obtained characterise the temperature subsystem and define a first step towards a methodology to deal with the thermal data that will be obtained during flight operations.
A COMPARISON OF AMC CARGO CHANNEL FLIGHTS AND ALTERNATIVE COMMERCIAL AIR FREIGHT CARRIERS.

Abstract : The purpose of this thesis is to analyze and compare the air freight rate structure of commercial air freight carriers and the U.S. Air Force's Air Mobility Command (AMC) in a peacetime environment. Research was conducted on six commercial companies and AMC routes, structures, and services. AMC's channel flight system, operated over specific heavy shipment routes, was used as a baseline for comparison purposes. Associated air freight services are examined to address possible value added properties from a Departrnent of Defense (DOD) perspective. From these analyses, a set of recommendations for utilizing AMC or commercial air freight assets for DOD air freight requirements is offered.

This study assessed morphometric of gullies in Nasarawa State. Soil erosion is among the most endemic environmental problems of modern times. Both primary and secondary sources of data were used for this study. As ample of 36 gully sites were carried out in three Local Government Areas representing the study area for this research work. Information on gullies morphometric, morphology, soil particles size and the coordinate of each identified gullies site were taken from the field. Instruments such as hand auger, global position system. (GPS), photograph, Abeny level, linen tape, ranging poles, pegs and measuring tape and field observation methods were also adopted. The results generated from the field were subjected to statistical and laboratory analysis. The results of the findings revealed that 44.4% of the gullies in the study area are discontinuous gullies, 55.6% were continuous gullies, while gullies in the study are at their 5% and above development. 58.3% of the sampled gullies were at a stable state of development, while 41.7% of the gullies were at an unstable state of development. It was also revealed that 38.9% of the sampled gullies in the study area were long-narrow gullies, while 22.2% were linear
TreePartNet: neural decomposition of point clouds for 3D tree reconstruction

We present TreePartNet , a neural network aimed at reconstructing tree geometry from point clouds obtained by scanning real trees. Our key idea is to learn a natural neural decomposition exploiting the assumption that a tree comprises locally cylindrical shapes. In particular, reconstruction is a two-step process. First, two networks are used to detect priors from the point clouds. One detects semantic branching points, and the other network is trained to learn a cylindrical representation of the branches. In the second step, we apply a neural merging module to reduce the cylindrical representation to a ﬁnal set of generalized cylinders combined by branches. We demonstrate results of reconstructing realistic tree geometry for a variety of input models and with varying input point quality, e.g., noise, outliers, and incompleteness. We evaluate our approach extensively by using data from both synthetic and real trees and comparing it with alternative methods
