A Space-Time Coded Mills Cross MIMO Architecture to Improve DOA Estimation and Its Performance Evaluation by Field Experiments
Ungan, Cahit Ugur; Candan, Çağatay; Çiloğlu, Tolga (2020-06-01)
Conventional Mills Cross architecture suffers from poor direction-of-arrival angle estimation accuracy in the dimension that the transmitter is aligned. To improve the estimation accuracy, a space-time coded, multiple-input multiple-output (MIMO) direction finding method, with complementary codes is presented. The performance of the suggested MIMO Mills Cross architecture has been evaluated by underwater field experiments. Field experiments confirm the feasibility of the proposed approach and illustrate the...

An adaptive simulated annealing algorithm-based approach for assembly line balancing and a real-life case study
Guden, H.; Meral, Fatma Sedef (2016-05-01)
In this study, we address the deterministic assembly line balancing problem (ALBP) in a multiple product-models environment with multiple objectives. We have been motivated by the assembly line balancing problem of a white goods product production line that is a multi-model type line with 68 stations through which four product-models are assembled, each with approximately 400 precedence relations and 300 tasks. In the plant, to cope with the increasing demand in the medium term, the efficiency of the line i...
A Method to Integrate Energy Harvesters into Wireless Sensor Nodes for Embedded In-Pipe Monitoring Applications
Qureshi, Fassahat U.; Muhtaroglu, Ali; Tuncay, Kağan (2015-03-26)
Batteries are commonly used to power sensors, a fact that carries severe drawbacks such as limited lifetime and regular replacement. Battery powered sensors are particularly impractical in under-water pipelines due to limited access. Therefore, harvesting of ambient energy to power embedded sensors is an attractive option for such systems. A method is proposed, in this paper, to power in-pipe wireless sensor nodes based on energy harvesting techniques, with minimal impact to the pipe performance. Based on t...
A double-porosity model for a fractured aquifer with non-Darcian flow in fractures
Altinors, Altay; Onder, Halil (Informa UK Limited, 2008-08-01)
Non-Darcian flow in a finite fractured confined aquifer is Studied. A stream bounds the aquifer at one side and all impervious Stratum at the other. The aquifer consists of fractures capable of transmitting water rapidly, and Porous blocks which mainly store water. Unsteady flow in the aquifer due to a Sudden rise in the stream level is analysed by the double-porosity conceptual model. Governing equations for the flow in fractures and blocks are developed using the continuity equation. The fluid velocity in...
