Communication problems between actors in construction projects

Communication is a fundamental part of a construction project. Like any fundamental piece, it must be done in an effective way to ensure the success of the project. Given its importance, understanding the relationship between the different actors involved in a project, analysing the problems that arise between them and investigating the best options to ensure its correct functioning is very important for any actor involved in construction projects. This thesis, therefore, has as main objective to investigate the problems of communication between the actors involved in construction projects. The thesis will answer the following questions: How does communication within a construction project work? What are the main communication problems that arise in a construction project? How are these problems solved, with what practices and tools? To solve these questions, a research will be done divided into two parts. The first part is an analysis of the existing literature on communication in construction projects. The second part is an empirical study conducted a qualitative analysis of twelve interviews. These interviews will be made to actors with extensive experience in the sector who have recently been involved in various construction projects. The results of the thesis indicate the importance of communication within a project and the use of good tools and practices to promote their effectiveness. In addition, the study indicates that there are several widespread problems in construction projects. There is an extended problem with documentation management, this problem is tried to be solved with the use of Information and Communication Technologies. The next problem arises from the informality of many of the communications and from not recording solutions and agreements. A good use of the tools and practices available to the actors involved in the project must solve this problem. The last problem observed and probably the most serious is a widespread communication problem derived by the dispute that seems to exist in the sector, between the construction company and the project management. Avoiding cuts in the budget and trying to avoid many changes with its consequent decrease in the quality of the project, should avoid this problem

Embedded System for Monitoring and Prevention of Hardware/Software Incidents in Data Center Devices

Cursos e Congresos, C-155[Abstract] Real-time monitoring of the status of the devices available in Data Centers (DC) is a critical task to try to provide quality services to customers, but also to detect possible hardware/- software incidents or to act against cyber-attacks. To perform these functions, there are specific system and network monitoring tools on the market that supervise different device functionalities (CPU, memory, storage, network, processes, services, etc.). However, these systems do not include the monitoring of basic elements for the correct operation of these devices, such as environmental parameters (power supply, temperature, humidity, noise, etc.). In this project we have designed and built a prototype embedded system, both hardware and software, to monitor in real time each device inside a rack and capable of integrating a wide variety of sensors. The hardware device is composed of: motherboard, power supply, infrared temperature sensor, noise level sensor, current consumption meter, 220VAC real input voltage meter, electronic module to switch on/off the 220VAC output and WiFi module to send the informationCITIC is funded by the Xunta de Galicia through the collaboration agreement between the Consellería de Cultura, Educación, Formación Profesional e Universidades and the Galician universities for the reinforcement of the research centres of the Galician University System (CIGUS)

Impact of short-term extreme temperature events on physiological performance of Salicornia ramosissima J. Woods under optimal and sub-optimal saline conditions

Increasing extreme temperature climatic events could exert an important effect on plant photosynthetic performance, which could be modulated by the co-occurrence with other environmental factors, such as salinity, in estuarine ecosystems. Therefore, a mesocosm experiment was designed to assess the impact of temperature events for three days (13/5 °C, 25/13 °C and 40/28 °C) in combination with two NaCl concentrations (171 and 1050 mM NaCl) on the physiological performance of Salicornia ramosissima. Extreme temperature events had a negative impact on S. ramosissima photosynthetic efficiency, this effect being more marked with cold wave at both salinities, compared with heat wave, even in presence of NaCl excess. This differential thermotolerance in the photosynthetic apparatus was ascribed to the greater integrity and functioning of its photosynthetic pathway at high temperature, as indicated by constant gs, Vc,max values at optimal salinity and the higher values of those parameters and gm recorded in combination with NaCl excess. Moreover, S. ramosissima was able to upregulate the energy sink capacity of its photochemical apparatus at elevated temperature and salinity by a greater energy excess dissipation capacity. This could have contributed to reducing the risk of oxidative stress, along with the recorded higher capacity for antioxidant enzyme activity modulation under these conditions.España, MINECO Project CGL2016– 75550-

Effect of an electric field within microscopy focused ion beam (FIB) between manipulator sharp and the ion trap of the electron detector

"The manipulation of samples with micro manipulators sharps in the normal axis to the observation plane is practically blind in microscopy focused ion beam (FIB) mono beam. The application of a negative potential to the manipulator sharp has been considered, which causes differences of electrical potential between the detector and the sample holder, generating an electric field between the sharp and the sample. This makes the electrons, aside the sample, undergo a greater deflection, reflecting in poorer contrast image. This deflection depends on a great extension of the sample holder height between the micromanipulator sharp, voltage deflector, q/m electron factor and electron acceleration.

Ethics, Emotion, and Aesthetics: Architecture After the Crisis of Modern Science

Alberto Pérez Gómez first came to prominence as an architectural theorist and historian with his 1983 publication, Architecture and the Crisis of Modern Science; a book that won the Alice Davis Hitchcock Award for distinguished scholarship in architectural history the following year. Having established himself as one of the architecture world's leading thinkers and most original historical theorists, he offered a book that completely broke all norms of either academic or architectural discourse; his 1992 treatise Polyphilo, or, The Dark Forest Revisited: An Erotic Epiphany of Architecture. The author and editor of numerous publications since, in 2007 he coauthored Towards an Ethical Architecture: Issues Within the Work of Gregory Henriquez, a publication "seeking to remind architects of the critical role they play in leading the creation of a community's collective space". In the first of these seminal texts he illustrated how architecture was profoundly transformed by the scientific revolution of the eighteenth century - and how the consequences of that revolution are still dominant in architectural practice and discourse today. The second investigates architectural 'beauty' through the prism of erotic desire. Described as treading the borders of fiction, theory, and pornography, it epitomizes Pérez-Gómez's desire to reframe architecture as an emotive, corporeal and visceral phenomenon in the context of today's scientific and material society. Running through these works is a constant argument that blurs the intellectual divisions of modern thinking – whether they be based on drawing a sharp distinction between the role of emotion and logic in architectural design; the part sentiments and feelings play in our use and understanding of the spaces we inhabit; or the divisions that have emerged in aesthetic and ethical theory that see the former as type of theorised formula and the latter as an isolated and fully quantifiable set of social practices. In addressing these issues, he begins this interviewarticle with comments on the phenomenological underpinnings in this thinking and his interest in both Edmund Husserl and Maurice Merleau-Ponty

Trend analysis and outlier distribution of CO2 and CH4: A case study at a rural site in northern Spain

Producción CientíficaCO2 and CH4 outliers may have a noticeable impact on the trend of both gases. Nine years of measurements since 2010 recorded at a rural site in northern Spain were used to investigate these outliers. Their influence on the trend was presented and two limits were established. No more than 23.5% of outliers should be excluded from the measurement series in order to obtain representative trends, which were 2.349 ± 0.012 ppm year−1 for CO2 and 0.00879 ± 0.00004 ppm year−1 for CH4. Two types of outliers were distinguished. Those above the trend line and the rest below the trend line. Outliers were described by skewed distributions where the Weibull distribution figures prominently in most cases. A qualitative procedure was presented to exclude the worst fits, although five statistics were considered to select the best fit. In this case, the modified Nash-Sutcliffe efficiency is prominent. Finally, three symmetrical distributions were added to fit the observations when outliers are excluded, with the Gaussian and beta distributions providing the best fits. As a result, certain skewed functions, such as the lognormal distribution, whose use is frequent for air pollutants, could be questioned in certain applications.Ministerio de Economía y Competitividad y fondos FEDER, (project numbers CGL-2009-11979 and CGL2014-53948-P

Features of the annual evolution of CO2 and CH4 in the atmosphere of a Mediterranean climate site studied using a nonparametric and a harmonic function

Concentrations of CO2 and CH4 measured over 3 years at a rural site in the Spanish northern plateau were investigated together with vegetation and meteorological variables. Two procedures were implemented to study the annual evolution. Kernel estimation provided a detailed time description, and the harmonic model may be fitted easily. The site was characterised by grass from autumn to spring. However, vigorous growth was observed during the latter season due to the biological cycle of plants under favourable meteorological conditions. A CO2 peak was observed a fortnight before the time of maximum NDVI, and was attributed to the prevalence of respiration over photosynthesis. A pronounced trough was apparent in summer and was explained by the death of vegetation and active dispersion in a highly developed boundary layer. CH4 evolution was characterised by a deficit period from May to October, indicating that meteorological evolution played a key role. The harmonic model showed that annual and half-annual cycles evidenced a similar contribution for CO2, whereas said weight for the half-annual cycle was considerably smaller for CH4.Ministry of Economy and Competitiveness and ERDF funds (grant numbers CGL2009-11979 and CGL2014-53948-P
