Simulation and Analysis of 45 GHz Millimeter-wave Propagation Characteristics in Living Room

In this paper, the characteristics of millimeter-wave propagation at 45 GHz in a living room are investigated based on simulation by the method of shooting and bounding ray tracing/image (SBR/IM). Path loss of co-polarization and crosspolarization is compared to verify the accuracy of simulation. The angle of arrival of different polarization is also revealed. Root mean square (RMS) delay spread of co-polarization and cross-polarization is studied. It is shown that the RMS delay of co-polarization is generally higher than that of cross-polarization in this environment. In addition, the influence of furniture on the propagation characteristics of radio waves in the line-of-sight (LOS) environment is discussed.

In fact, most thoughtful people recognize this. Nevertheless, it was slightly surprising to discover that John Maynard Keynes gave a talk on this very subject to the secret society known as The Apostles in Cambridge University in 1909. But why should we have been surprised? Keynes was incredibly smart by any standard, so it was probably as natural that he should consider the influence of furniture on love, as he might address issues of monetary policy, elasticity of demand, or the law of diminishing returns. The manuscript of this talk lay in Keynes’s papers at King’s College Cambridge and is published here for the first time as one of our Primary Source Texts.The articles in this issue are more widely dispersed than usual; from eighth-century Northumbria to eighteenth-century India, and on to antebellum Philadelphia and postwar Glasgow. Each of these articles examines different media deploying a variety of techniques. Ben Tilghman considers the processes of laying out manuscript pages in the early Middle Ages and how this affects their meaning; Siddhartha Shah traces the changes in symbolism and status that a highly prized diamond undergoes when translated from the Punjab to Britain, from the armlet of Duleep Singh to the crown jewels of Queen Victoria via the Great Exhibition of 1851; Anne Verplanck aims to put some of the people involved in early American portrait photography back into the picture in her study of daguerreotypes in Philadelphia; and Glenn Hooper considers the ways in which design and new materials played a role in re-establishing the British furniture industry in the wake of the Second World War by tracing the business history of one firm, Morris and Co. of Glasgow, between 1948 and 1958.The book and exhibition reviews in this issue are similarly wide-ranging. In England alone, we move from the glorious survivals of medieval embroidered vestments to the equally spectacular psychedelic clothing of the later 1960s, and from a single Lithuanian boot in Cambridge to the occasionally conflicting advice on home decorating in the Aesthetic Movement. Alongside this, one can find discussions of simulacra in medieval Germany, the autobiography of the Viennese émigré Paul Frankl, and a retrospective exhibition of the work of the French furniture and interior designer Pierre Paulin.

Objective approach for analysis of noise source characteristics and acoustic conditions in noisy computerized embroidery workrooms

It is highly important to analyze the acoustic properties of workrooms in order to identify best noise control measures from the standpoint of noise exposure limits. Due to the fact that sound pressure is dependent upon environments, it cannot be a suitable parameter for determining the share of workroom acoustic characteristics in producing noise pollution. This paper aims to empirically analyze noise source characteristics and acoustic properties of noisy embroidery workrooms based on special parameters. In this regard, reverberation time as the special room acoustic parameter in 30 workrooms was measured based on ISO 3382-2. Sound power quantity of embroidery machines was also determined based on ISO 9614-3. Multiple linear regression was employed for predicting reverberation time based on acoustic features of the workrooms using MATLAB software. The results showed that the measured reverberation times in most of the workrooms were approximately within the ranges recommended by ISO 11690-1. Similarity between reverberation time values calculated by the Sabine formula and measured values was relatively poor (R (2) = 0.39). This can be due to the inaccurate estimation of the acoustic influence of furniture and formula preconditions. Therefore, this value cannot be considered representative of an actual acoustic room. However, the prediction performance of the regression method with root mean square error (RMSE) = 0.23s and R (2) = 0.69 is relatively acceptable. Because the sound power of the embroidery machines was relatively high, these sources get the highest priority when it comes to applying noise controls. Finally, an objective approach for the determination of the share of workroom acoustic characteristics in producing noise could facilitate the identification of cost-effective noise controls.

The influence of furniture and equipment layouts on airflow pattern in a clean room

The layout of the production line in any clean rooms will change according to the production process and this posed a problem for post clean room maintenance. Air velocity is one of the many problematic issues commonly found in clean room environment. It is important to address this on-going problem whenever there is an upgrading of the production process in which more advanced equipment were being introduced to the clean room to automate the process. This paper examines the characteristics of airflow distribution within the clean room due to changes in the production process. This study was conducted for a class 100 clean room at a disk-drive manufacturing firm. The airflow distribution in the clean room was simulated using computational fluid dynamics (CFD) software. This model provides a valuable insight into the processes that are difficult and time-consuming to study experimentally. The results showed that furniture such as a workbench and a laminar flow hood have great impact on the airflow pattern in the clean room. The predicted airflow results offered substantial benefits in the design and development of a better furniture layout plan that eradicates any of the possible turbulence problems.

A Study of the Influence of Furniture on the Thermal Behaviour of Interior Thermal Mass

Present day thermal behaviour models assume direct solar energy entering a room through windows to be evenly distributed over room surfaces, but in reality the distribution depends on window positions and interior furniture. This paper describes a study of the shading effects of furniture on the thermal behaviour of interior thermal mass. A computer program which tracks sunlit patches and shaded areas in a rectangular room with furniture was developed. For every hour, the amount of direct solar heat received by room surfaces can be determined. An example of the effect of furniture shadows on energy distribution on interior room surfaces is presented. At this stage, it appears that the furniture could have a significant influence on the distribution of energy received by room surfaces.
