Um estudo sobre as causas de atrasos de obras de empreendimentos imobiliários na região Metropolitana de São Paulo

O artigo tem como objetivo elencar as principais causas de atrasos de obra que se verificam atualmente em empreendimentos imobiliarios no Brasil. Buscou-se primeiramente uma identificacao teorica, atraves de revisao bibliografica, das principais causas que afetam as obras fora do pais, com enfase em paises em desenvolvimento, e que possivelmente apresentam condicoes e dificuldades similares as encontradas pelos empreendedores e construtores brasileiros. Com base nesta relacao de motivadores de atrasos, estabeleceu-se uma classificacao e correlacao, identificando-se as possiveis causas. Este referencial foi utilizado para a uma pesquisa analitica em 32 obras imobiliarias executadas na regiao metropolitana de Sao Paulo nos ultimos 7 anos. Os resultados mostram que, apesar de interferencias de empreendedores afetarem significativamente os projetos, ao menos nestes empreendimentos, os principais problemas parecem estar relacionados muito mais as questoes internas e de organizacao dentro do canteiro de obras pelos gestores das construtoras, do que a questoes externas ao ambiente de execucao (chuvas, solo, variacoes de mercado, fornecedores, envolvimento dos clientes, etc.), o que reforca cada vez mais a importância do investimento em qualificacao de pessoas, sistemas e metodologias, mesmo que simplificados, de planejamento e controle de obras.
Where the Wild Things Are: Evolving Futures of Communications Regulation in the Current National Security Context

In March 2008, the Australian Communications and Media Authority (ACMA) released a report dealing with the possible implications of the 'top six trends' in communications and media technologies, applications and services. The report highlights the fact that key regulatory elements in the communications environment are being conceptually 'stretched and pulled' by the accelerating pace of change in communications technologies, applications and services. The report also notes that in the longer term, there will be increasing overlapping developments in technology and increasing interconnections between people, databases and objects. This article will explore the evolving futures of communications regulation in the current national security context by focusing on the post-'9/11' regulatory response in Australia. Communications have long been regarded as 'the fundamental cornerstone of intelligence and law enforcement'. For this reason, in the current national security context, this article will argue that the evolving futures of communications regulation will be increasingly calibrated with national security policy.
Manure and Runoff Water Quality from Feedlots as Affected by Diet and Pen Surface

Environmental management of confined animal feeding operations is closely regulated. Hence, understanding management practices that affect nutrient outputs and the potential risk of transport in the environment is of importance. The objective of this research was to evaluate the impact of feeding corn-based wet distillers grains plus solubles (WDGS) and the type of pen surface material on manure nutrient composition and runoff water quality. Rainfall simulations were conducted at an experimental feedyard that contained soil and fly ash surfaced pens. Two diets, steam-flaked corn (SFC) and 30% WDGS, were fed to cattle on each surface type. Diets containing WDGS resulted in greater manure nitrogen (N) and phosphorus (P) concentrations than SFC diets. Runoff volumes were significantly higher from soil pens where WDGS diets were fed. Runoff volumes were consistent for fly ash pens; however, there was a 3-fold difference between soil surfaced pens, indicating great variability between soil surfaced pens. Feeding WDGS increased soluble reactive P (SRP) concentrations in runoff water by 38% and total P concentrations by 27% compared to SFC. This increase in P runoff concentrations as a result of feeding WDGS was expected, as manure WEP concentrations were greater in pens where WDGS was part of the diet. Pen surfaces with fly ash resulted in increased total P and ammonium-N (NH4-N) concentrations in runoff water. Mass losses of SRP, total P, NH4-N, and total Kjeldahl N (TKN) were highest from soil surfaced pens in which cattle were fed WDGS. While manure nutrient concentration can be an excellent indicator of the potential of nutrient runoff, hydrological properties can be the single most important factor in actually transporting nutrients offsite.
Effects of Structure Parameters on Performance of DSPM Motor

A novel flux switching external rotor doubly salient permanent magnet (DSPM) motor was researched. The two-dimensional model of the motor was established by Ansoft motor design software and the effects of air gap length and rotor pole arc on motor performance were discussed. The simulation results show that larger or smaller air gap length and rotor pole arc improve the torque ripple rate, but the increase of air gap length is helpful to enhance the overload capacity. The conclusions of this article have positive significance for improving the motor performance.
A CMOS Radio-Frequency Front-End for Multi-Standard Wireless Communications.

The explosive growth of wireless communication market has led the development of low-cost, highly-integrated wireless communication systems. Even though most blocks in the front-end have successfully been integrated by using the CMOS technology, it is still a formidable challenge to integrate the entire front-end. Thus, the objective of this research is to demonstrate the feasibility of the integrated front-end by using improved circuit techniques as well as the improved process technologies. This dissertation proposes an improved control scheme to enhance the high-power handling capability of an antenna switch. As a part of this research, an antenna switch controller for a GaAs antenna switch was first developed to enhance the performances of the GaAs antenna switch by using the boosted control voltage. To enhance the efficiency of the front-end, efficiency improvement techniques for the antenna switch controller has also been studied. With the suggested efficiency improvement techniques, a fully-integrated antenna switch was implemented using the SOI technology, and exceeding performances over many commercial products for watt-level high-power applications have been successfully demonstrated. As an effort to improve the efficiency of a power amplifier, a linear envelope detector was also implemented, and the results show that the envelope detector is suitable for dynamic biasing of the power amplifier. The research presented in this dissertation, thus, provides a low-cost and high-performance solution for highly-integrated RF front-end used in various wireless communication systems.
Irrigation Technology and Water Conservation in the High Plains Aquifer Region

Plains aquifer is perhaps the largest single water management concern in the United States. The aquifer underlies some 173,000 square miles (Zwingle 1993) spanning portions of the eight states of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. In most of this region, the aquifer is the primary water source for irrigation, household, and municipal uses, with irrigation being the largest use representing over 85 percent of annual withdrawals (U. S. Geological Survey 1995). Ever since irrigation became widespread in the latter half of the twentieth century, the aquifer has been overdrafted and the water in storage has been in a steady state of decline. As much as 40 percent of pre-development storage has been depleted in the most agriculture-intensive areas of the aquifer (Feng and Seggara 1992). A common policy prescription to conserve ground water and reduce the rate of decline is the provision of subsidies for more effi cient irrigation technologies (Johnson et al. 2001). This policy has been implemented in the High Plains region at both the state and federal levels. One such policy administered by the state of Kansas is a cost share program that pays a portion of an irrigator’s investment to upgrade technology on an irrigated fi eld – for example by switching from a fl ood system to a center pivot system (Golden and Peterson 2006). Since the 2002 Farm Act, the federal Environmental Quality Incentives Program includes cost share contracts for water conservation that can be used to subsidize technology upgrades. Although more modern irrigation technologies are known to improve farmers’ profi ts and reduce production risk (Earls and Bernardo 1992, DeLano and Williams 1997, O’Brien et al. 2000, Peterson and Ding 2005), some have questioned whether they in fact reduce consumptive water use. Several authors have shown that, under certain conditions, farmers with a more effi cient irrigation system have an incentive to increase consumptive use (Huffaker and Whittlesey 1995, 2003, Whittlesey 2003) either by expanding irrigated acreage, or increasing net irrigation per acre with a more water intensive crop. In this paper, we conduct a series of detailed simulations of irrigated crop production in the Kansas High Plains to assess the impact of irrigation technology on water use. We compare the water use, irrigation effi ciency, and economic performance of common production scenarios under both technologies. The simulations account for the timing of irrigation and weather events during the growing season as well as the variability of weather conditions across years. Our performance measures refl ect averages over a 37year period of observed weather in the study region. The crop production scenarios differ by irrigated acreage and the irrigated crop choice to highlight the effect of these factors on overall water use.
DENSE NETWORK TRAFFIC MODELS, TRAVEL TIME RELIABILITY AND TRAFFIC MANAGEMENT. II: APPLICATION TO NETWORK RELIABILITY

This paper is the second of a pair of papers discussing two main themes concerning dense network modelling. These themes are: (1) the changing nature of traffic management technology and the underlying objectives behind traffic management practice, and (2) the use of measures of network reliability in models, especially as an element of the evaluation of alternative network configurations. This paper develops and applies the second theme, the use of network reliability concepts in the evaluation of traffic networks, through consideration of variations in travel times, distinction between local street and arterial road networks, and the definition and application of a set of reliability indices that may be used to study different trip movements in a network. It indicates how these indices may be used in appraising different traffic management plans for a dense network of local streets and arterial roads, using a case study application.

IoT-Based Health Big-Data Process Technologies: A Survey

Recently, the healthcare field has undergone rapid changes owing to the accumulation of health big data and the development of machine learning. Data mining research in the field of healthcare has different characteristics from those of other data analyses, such as the structural complexity of the medical data, requirement for medical expertise, and security of personal medical information. Various methods have been implemented to address these issues, including the machine learning model and cloud platform. However, the machine learning model presents the problem of opaque result interpretation, and the cloud platform requires more in-depth research on security and efficiency. To address these issues, this paper presents a recent technology for Internet-of-Things–based (IoT-based) health big data processing. We present a cloud-based IoT health platform and health big data processing technology that reduces the medical data management costs and enhances safety. We also present a data mining technology for health-risk prediction, which is the core of healthcare. Finally, we propose a study using explainable artificial intelligence that enhances the reliability and transparency of the decision-making system, which is called the black box model owing to its lack of transparency.
A 3D Model for Eddy Current Inspection in Aeronautics: Application to Riveted Structures

Eddy current technique is currently an operational tool used for fastener inspection which is an important issue for the maintenance of aircraft structures. The industry calls for faster, more sensitive and reliable NDT techniques for the detection and characterization of potential flaws nearby rivet. In order to reduce the development time and to optimize the design and the performances assessment of an inspection procedure, the CEA and EADS have started a collaborative work aiming at extending the modeling features of the CIVA non destructive simulation plat‐form in order to handle the configuration of a layered planar structure with a rivet and an embedded flaw nearby. Therefore, an approach based on the Volume Integral Method using the Green dyadic formalism which greatly increases computation efficiency has been developed. The first step, modeling the rivet without flaw as a hole in a multi‐stratified structure, has been reached and validated in several configurations with experimental data.
The relationship of preoperative and postoperative serum CEA and CA 19-9 levels with tumor localization, stage and overall survival in patients with colorectal cancer

Aim: To evaluate the prognostic value of pre/postoperative serum levels of Carcinoembryonic antigen (CEA), Carbohydrate antigen 19-9 (CA 19-9), and their relationship with primary localization and stage of colorectal cancer (CRC) patients. Materials and Methods: 255 patients who underwent curative or palliative surgery with the diagnosis of CRC between 2015 and 2020 were included in the study. The patients were divided into groups as right colon tumor and left colon tumor based on the region of the primary tumor. Baseline data on age, sex, location of primary tumor, disease stage, histological differentiation, BRAF and RAS mutation situations and serum CEA and CA 19-9 levels were recorded before and after surgery. Individuals were followed for at least sixty months or until they died. Overall survival (OS) and Disease Free Survival (DFS) rates were estimated using the Kaplan–Meier method. Results: 103 patients had right sided (41.4%) and 152 patients (59.6%) had left sided CRC. Most of the patients were in the early stage (71%). DFS and OS patients with left colon tumors were longer than the right. [(DFS, 32.18 (6-60) vs. 34.25 (6-60) months, p=0.332) and (OS, 41.16 (6-60) vs. 49.05 (11-60) months, p=0.002]. An assessment of the prognosis showed that the OS was significantly worse in the patients with a high CEA level (p=0.001) and in the patients with a high CA 19-9 level (p=0.001). In multivariate analysis, normal serum CA 19-9 levels (p=0.002), RAS wild type tumor (p<0.001), early stage disease (p=0.004) were identified as a good prognostic factors for OS of these patients. Conclusion: It was determined that left colon tumors had a longer life span than right side. Elevated levels of CEA and CA 19-9 pre and postoperative in CRC have a worst prognosis than those with normal levels of these markers.
Implementation of a wavefront coded imaging system using a spatial light modulator

We present the results of the utilization of a Spatial Light Modulator Liquid Crystal Display for the implementation of wavefront codification procedures in an imaging system. The light modulator works in transmission mode at the pupil of the instrument. The main disadvantage is that the procedure implies a calibration of the device as well as an inherent image processing. The more interesting feature we can obtain is the versatility related to the use of an electronic device at the pupil, as compared with conventional (fixed) manufactured ones.
Advances in Canadian Research Coupling Hydrology and Water Quality, 2003-2007

Canada is a country of considerable fresh water resources, with a mature community of hydrologists whose research is concerned with the transport and fate of nutrients and other pollutants that impact water quality, either from a human use or ecosystem perspective. This work has led to important advances in understanding that have contributed to regulatory action with sometimes global impact. However, water quality issues persist, largely due to increased natural resource extraction, land-use change, climate change and the identification of emerging contaminants of concern. This paper highlights important advances by Canadian researchers coupling hydrology and water quality over the period 2003-2007.
Indoor Positioning System using Incident Angle Detection of Infrared sensor

In this paper, a new indoor positioning system based on incident angle measurement of infrared sensor has been suggested. Though there have been various researches on indoor positioning systems using vision sensor or ultrasonic sensor, they have not only advantages, but also disadvantages. In a new positioning system, there are three infrared emitters on fixed known positions. An incident angle sensor measures the angle differences between each two emitters. Mathematical problems to determine the position with angle differences and position information of emitters has been solved. Simulations and experiments have been implemented to show the performance of this new positioning system. The results of simulation were good. Since there existed problems of noise and signal conditioning, the experimented has been implemented in limited area. But the results were acceptable. This new positioning method can be applied to any indoor systems that need absolute position information.
Study of a dual‐band packaged patch antenna on a PC card for 5–6 GHz wireless LAN applications

A study of a dual‐band PC card mounted folded microstrip patch antenna is presented for use with a laptop computer. The antenna operates in the wireless local area network (WLAN) bands from 5.15–5.35 GHz and from 5.725–5.825 GHz within 2.5:1 VSWR. Three cases are considered. First, the PC‐card‐mounted antenna is studied without a laptop. Next, it is attached externally to a laptop and its characteristics are analyzed. Finally the antenna is studied as packaged within a laptop. Detailed antenna characteristics, including current distribution, VSWR, radiation pattern, and gain, are given. © 2003 Wiley Periodicals, Inc.

An analytical model for fully depleted single gate SOI MOS transistors including lattice temperature effects

An analytical model for fully depleted SOI MOSFETs is presented. Major small geometry effects such as carrier velocity saturation, mobility degradation, channel length modulation, and drain induced barrier lowering are included. Device self heating due to low thermal conductivity of a buried oxide layer is included in carrier mobility modelling. Thermal effects are also included in threshold voltage expression. Source, drain, and channel resistance effects are also included. Modelled results are then compared to available measured data and are shown to be in very good agreement.
PtSi Infrared Area Array Utilizing MOS/CTD Readout

We describe the operation, construction, and performance of an infrared focal plane array that utilizes platium silicide Schottky-barrier diodes on p-type silicon as the infrared sensor and has a MOS/CTD readout structure. The i28 X 128 element array is fabricated using standard integrated circuit grade silicon and NMOS processing. Associated with each photoelement there is a MOS multiplexer switch. Parallel connection of every multiplexer switch in a row allows a digital shift register to address one row of diodes at a time. The video signals are parallel transferred through common column video lines into two bucket-brigade device (BBD) charge transfer registers for signal readout. This readout structure has the advantages of high fill factor, low noise, and large charge handling capacity. In addition, the digital scan register and the BBD registers are less susceptible to freeze-out at temperatures below 40 kelvin than a buried-channel CCD.

Att förstärka barnperspektivet på en vuxenpsykiatrisk avdelning - angeläget, men svårt

Barn till foraldrar med psykisk sjukdom har en okad risk att sjalva drabbas av psykiska och andra problem. Trots det har vuxenpsykiatrin ofta forsummat att uppmarksamma patienters barns situation. Tillagg till Halso- och sjukvardslagen innebar att sjukvardspersonal ar alagda att beakta patienters barns behov av stod nar foraldern har psykisk storning. Vi undersokte slutenvardspersonalens attityder och erfarenheter av att arbeta med barnperspektivet samt huruvida en kortare utbildningsintervention kan paverka handlingsberedskapen. Semistrukturerade intervjuer som genomfordes pa tre psykiatriska avdelningar, foljt av kvalitativ innehallsanalys, visade att barnperspektivet anses vara ett angelaget men i praktiken svart omrade och att strukturerade arbetsmetoder och omfattande utbildning kravs for att arbetet ska komma igang.
