Improving Regression Performance on Monocular 3D Object Detection Using Bin-Mixing and Sparse Voxel Data
No full textAccurate and fast 3D object detection plays a role of paramount importance for safe and capable autonomous machines. LiDAR point cloud based methods have demonstrated impressive results, yet expensive LiDAR sensors make such approaches infeasible for wide-scale adaptation. Camera based methods on the other hand are performing sub-optimally given safety and accuracy requirements. Traditionally, camera based 3D object detection is performed by generating pseudo-LiDAR point clouds from RGB-D data and using point-cloud based models, however, irregular nature of point cloud data representation makes it challenging to exploit spatial local correlations on 3D space and point cloud based models generally suffer from this. To this end, we propose Sparse Voxel based 3D Object Detection, our approach differs from traditional approaches by converting point cloud information to sparse voxel grid and utilizing sub-manifold sparse convolutions to extract information instead of PointNet based models. Furthermore, we propose Bin-Mixing layers. Bin-Mixing replaces the output layer of a neural network and boosts performance by representing the problem of regression in a fashion that is easier for network to learn
MedSpecSearch: Medical specialty search
No full textMedSpecSearch (www.medspecsearch.com) is a search engine for helping users to find the relevant medical specialty for a doctor visit based on users’ description of symptoms. This system is useful for users who are not sure of which medical specialty they should consult to. Furthermore, the API of the search engine can be used as part of the online doctor appointment and medical consultation sites to route the patient or question to the right medical specialty. The system returns the top three relevant specialties when the estimated confidence score is high. Otherwise, it asks users to input more data.Türk Telekom R&D Center

It is also possible that the studies in this discipline, whose exact boundaries cannot be mentioned, can address these three items together, or two or only one of them. This discipline, which emphasizes the similar and different sides of the texts, also emphasizes the causes of differences and similarities. This branch of science, which sees literature as a whole, aims to find all possible affinities of intercultural and intertextual relations and their reasons in works of different or the same period. In this context, the main criterion is that suitable motifs or thoughts can be handled in a common context in terms of comparability. In this study, Les Fleurs du Mal of Charles Baudelaire; The poem titled a Conversation Between God and Man by Muhammed Ikbal and the art poem of Arif Nihat Asya was primarily studied thematically. Different and common aspects of the texts were emphasized. The 'Pluralist Method' used in comparative literature science was taken as the basis.Karsilastirmali edebiyat bilimi, farkli uluslara ya da ayni ulus veya ayni yazara ait en az iki eserin konu, düsünce ve biçim açisindan incelenmesini esas alir.

A secure and efficient inventory management system for disasters
No full textOver the last three decades, disasters worldwide claimed more than 3 million lives and adversely affected the lives of at least 1 billion people (Noji, 1997). Regarding the threats posed by these disasters, emergency disaster management has emerged as a vital tool to reduce the harm and alleviate the suffering these disasters can cause to their victims. A significant task of planners involved in emergency disaster management is planning for and satisfying the vital needs of the people located in emergency shelters such as the Superdome in New Orleans. This thesis proposes a novel and comprehensive framework for the development of a humanitarian emergency inventory management system based on the real-time tracking of emergency supplies and demands through the integration of emerging technologies such as Radio Frequency Identification Devices (RFID) for commodity tracking and logistics. The novelty of this thesis is that, for the first time in the emergency inventory management field, the proposed approach combines an offline planning strategy with online control techniques in a unified framework. Within this framework, the offline planning problem is solved by the stochastic humanitarian inventory management approach, whereas the online modeling strategies include the application of neural network-based functional approximation, simultaneous perturbation stochastic approximation (SPSA), and continuous time model predictive control (CMPC) techniques. Unlike previous studies, the flexibility of the proposed inventory management and control model allows the application of the developed mathematical model to extreme events making online real-time tracking possible. Realistic case studies built using information available from past disasters are used to examine the differences in inventory strategies for different types of disasters based on the impact area and duration of the extreme event. The proposed methodology is also capable of representing and understanding real-life cases where uncertainty and limitations on the inventory levels and flow of supplies can be modeled by introducing different levels of stochasticity and real-life constraints. The overall findings of this thesis have pointed out that the proposed integrated framework can be efficiently used for emergency inventory planning and inventory control during disaster relief operations without ignoring the real-world uncertainties, fluctuations, and constraints of disaster conditions.Ph.

Küresel stratejiler ve stratejik işbirlikleri
No full textEren, Erol (Dogus Author)Bilindiği üzere 20. yüzyılın sonlarından itibaren küreselleşme olgusu işletmecilik yaşamına damgasını vurmuş bulunmaktadır. 21. yüzyılın başlarında uluslararasılaşma ve çok ulusluluk yerine küresel firmaların etkinliğinden bahsedilmekte, rekabette yerel nitelikli rakiplerden çok küresel özellik taşıyan rakiplerden söz edilmektedir. Küresel firmalar çok miktarda standart üretimlerinin sağladığı ölçek ekonomileri, güçlü üretim teknolojileri ve dünyanın her yanından temin ettikleri üretim kaynakları ile düşük maliyetli ve kaliteli üretim yapabildikleri gibi güçlü mali yapıları ile ürün yenilikleri için gerekli araştırma ve geliştirme fonlarına ve kadrolarına sahip olmaktadırlar. Dünyanın her yerinde yerel işletmeler, güçlü küresel firmalarla ya stratejik işbirliğine yönelmekte ya da bu devler tarafından satın alınmaktadır. Aynı olgulara özellikle, dört beş senedir ülkemizde de rastlamaktayız . Bu makalemizde, küresel firmaların özelliklerini, firmaları küreselleşmeye yönelten nedenleri, küreselleşmenin yarar ve sakıncalarını, küresel firmaların izledikleri stratejik işbirliği biçimlerini ve strateji seçimlerinde uygulanan teknikleri incelemeye teorik alanda ve uygulamada çalışanlara bilgi sunmaya çalışacağız
