Published: July 2022

Son yıllarda gerek Dünya’da gerek Türkiye’de meydana gelen yangınlar, seller, şiddetli kasırgalar gibi doğal afetler artmakla birlikte çevreyi tehdit etmektedir. Bu felaketler doğal sistemin bozulduğunu ve ciddi çevre sorunlarının oluştuğunu göstermektedir. İklim değişikliğiyle artış gösteren ve doğal çevreye zarar veren bu sorunların oluşmasında yapılı çevrenin de büyük bir etkisi vardır. Doğal çevreye zarar veren ve çevreyi kirleten yapılaşmalar artmaktadır. Doğal ekosistemin dengesini bozan bu yapılaşmaların önüne geçmek için bina tasarımların ve uygulamaların çevreye duyarlı olmasına önem verilmelidir.
Çalışmada iklim değişikliği karşısında sürdürülebilir binaların önemi vurgulanırken bütünleşik tasarımın sürdürülebilir binaları oluşturmada ne kadar etkili olduğu üzerinde durulmuştur. Entegre tasarımı sağlamak ve proje aşamasında analizler yapmak için Yapı Bilgi Modellemesi (BIM) ele alınmıştır. BIM tasarımın ilk adımından itibaren multidisipliner bir çalışmayla sistemler arası etkileşime dayalı bütünleşik bir yaklaşımla binanın bir bütün olarak performansının optimize edilmesini sağlamaktadır. Sürdürülebilir tasarımı destekleyen BIM uygulamalı analiz çeşitleri açıklanmıştır. Bu analizler için yapılan simülasyonlar daha sürdürülebilir yüksek performans sağlayan binalar belirlemekte ve ilkim değişikliğinin etkisini azaltmaktadır.
Sonuç olarak iklim krizini önlemek veya etkisini azaltmak için sürdürülebilir binalar bütünleşik bir sistemle tasarlanıp proje aşamasında BIM destekli yazılımlar ve analiz araçların kullanılması teşvik edilmelidir. Binaların performanslarını değerlendirmek için BIM destekli analiz yazılımlarının mimari tasarımın farklı aşamalarına entegre edilmesi önerilmektedir. Böylece kullanıcıların sağlık ve konforunu korumanın yanında kaynakların da korunup gelecek nesillere aktarılması sağlanabilir.

Alternative Method to Determine the Amplitude of Limit Cycles of a Class of Nonlinear Electrical Circuit Oscillators
Authors: Barbi Ivo 
Published: July 2022

<p>This paper provides contributions to the study of weakly nonlinear electrical circuit oscillators. A method is introduced for the determination of the stable limit cycle and the dynamics of a family of oscillators, employed in the analysis of a nonlinear oscillator similar to the van der Pol circuit. The circuit studied includes the power dissipated in the inductor resistance and in a load resistor connected in parallel with the capacitor, along with a more generic nonlinear damping system. It is demonstrated that the system has a stable limit cycle which is dependent on the internal power losses. The results of the theoretical analysis are verified with the use of computer simulation.</p>
Human Activity Recognition Using Cascaded Dual Attention CNN and Bi-Directional GRU Framework
Authors: Ullah Hayat , Munir Arslan 
Published: July 2022

<p>Vision-based human activity recognition has emerged as one of the essential research areas in video analytics domain. Over the last decade, numerous advanced deep learning algorithms have been introduced to recognize complex human actions from video streams. These deep learning algorithms have shown impressive performance for the human activity recognition task. However, these newly introduced methods either exclusively focus on model performance or the effectiveness of these models in terms of computational efficiency and robustness, resulting in a biased tradeoff in their proposals to deal with challenging human activity recognition problem. To overcome the limitations of contemporary deep learning models for human activity recognition, this paper presents a computationally efficient yet generic spatial-temporal cascaded framework that exploits the deep discriminative spatial and temporal features for human activity recognition. For efficient representation of human actions, we have proposed an efficient dual attentional convolutional neural network (CNN) architecture that leverages a unified channel-spatial attention mechanism to extract human-centric salient features in video frames. The dual channel-spatial attention layers together with the convolutional layers learn to be more attentive in the spatial receptive fields having objects over the number of feature maps. The extracted discriminative salient features are then forwarded to stacked bi-directional gated recurrent unit (Bi-GRU) for long-term temporal modeling and recognition of human actions using both forward and backward pass gradient learning. Extensive experiments are conducted on three publicly available human action datasets, where the obtained results verify the effectiveness of our proposed framework over the state-of-the-art methods in terms of model accuracy and inference runtime across each dataset. Experimental results show that the proposed framework attains an improvement in execution time up to 167× in terms of frames per second as compared to most of the contemporary action recognition methods. </p>

Published: July 2022

<p>An all-metal reflectarray (RA) element based on the variable-rotation technique (VRT) is presented in this letter. The RA element, based on an elliptical inner conductor and a circular outer conductor, exhibits a continuous 360° phase coverage with negligible element loss over a wide range of incident angles and frequencies. A 10GHz prototype with 121 manually rotated elements was simulated, fabricated and tested. The proposed RA antenna has 2-D beam-steerable capability up to 45° elevation angle. The measured results agree well with the simulated counterparts. For demonstration, four different steering cases are presented as examples by manually adjusting the rotation angle of the RA elements. The maximum measured antenna gain is 26.2dBi, corresponding to an aperture efficiency of 66%. A 1.3 dB gain drop was measured during beam scanning from 0° to 40°. </p>

Published: July 2022

Albedo is a key component of the atmospheric, climatologic and remote sensing studies by means of global warming, energy balance, evapotranspiration, climate models, hydrological cycle etc. For these reasons, the accurate determination of surface albedo has become more important. In this study, the variation of measured albedo values of winter wheat, barley and sunflower cultivars according to phenological stages was investigated for the first time in the northwestern part of Turkey. Additonally, influences of leaf area index as growth indicator and rainfall as meteorological variable on albedo were also analyzed. The average albedo values of winter wheat, barley and sunflower in both growing periods varied from 0.176 to 0.190 for winter wheat, from 0.171 to 0.189 for sunflower and from 0.187 to 0.214 for barley cultivars. According to phenological stages, the minimum and maximum average albedo values were found for winter wheat as 0.121 between sowing and germination and 0.247 between stem formation and head emergence; for sunflower as 0.150 between sowing and germination and 0.212 between leaf initiation and immature bud; for barley as 0.144 sowing and germination and 0.261 between head emergence and flowering stages. Additionally, significant relationships were found between albedo and leaf area index for winter wheat, barley and sunflower as r2=0.87, r2=0.82 and r2=0.77, respectively.
