A microgrid is a power grid consists of distributed power generation units and loads. Microgrid is also a system that can operate in grid-connected mode and islanding (autonomous) mode. The control of distributed power generation units in microgrids is necessa…
Bu çalışmanın amacı, dünyada ilk 10’a giren ve hisse değerlerine ulaşılabilen düzenli hat taşımacılığı yapan 8 şirketin hisse değerlerinde etkin piyasa hipotezinin geçerli olup olmadığının tespit edilmesidir. Bu doğrultuda, zayıf formda etkin piyasa hipotezi…
This paper explores how intra-day volatility behaves across different weekdays during periods of major financial stress, focusing specifically on the S&P 500 and NASDAQ-100 indices. The analysis spans two significant market disruptions—the 2008 Global Financia…
The marketing strategy is concerned with the creation of the target market selection and necessary marketing mix in order for the businesses to achieve their marketing objectives. Marketing creativity includes creative applications in solving marketing problem…
Optimal reactive power flow and economic power dispatch is very important in power systems. Optimal reactive power flow provides minimum active power loss and economic power dispatch provides minimum active power generation cost in power systems. This study pr…
The use of alternative energy sources has begun to increase with the ever-increasing demand for energy. Today, with this increase, energy production is being tried to be obtained from alternative energy sources. Many companies have included the installation of…
Market democratization through conversational AI represents a critical frontier in financial technology, yet cryptocurrency analysis remains dominated by institutional players with sophisticated toolchains. We introduce AICrypto-Assistant, the first open-sourc…
We developed a series of financial social media sentiment analysis models starting with PyFin-Sentiment, a recent state-of-the-art domain-specific large language model for the financial domain. We focused on label accuracy and improvements in the quality and q…
İş yaşamında gerçekleşen gelişmeler sayesinde işletmeler müşteri odaklı, rekabet odaklı ve çevresel faktörleri ön plana çıkaran anlayış ile faaliyetlerini gerçekleştirmektedirler. Girişimsel pazarlamayı bu boyutların yanı sıra değişen çevresel koşullara hızlı…
The unlimited nature of consumption and needs contrasts with the scarcity of usable resources, necessitating the optimal use of available resources. Alongside the careful protection of the environment and human health, it is crucial to meet needs with maximum …
Bu çalışmada, non-lineer ve dengesiz yükün bulunduğu güç sisteminde aktif filtre kullanılarak harmonik distorsiyonun değeri düşürülmüştür. Pasif harmonik filtrelerin aksine, modern aktif harmonik filtreler, güç faktörü düzeltme, gerilim regülasyonunu saglama…
Elektrik sistemlerinin arızasız ve güvenli bir şekilde çalışabilmesi, akım ve gerilim gibi devre büyüklüklerin 50 Hz frekansta ve sinüsoidal formda olmasına bağlıdır. Bununla birlikte bir çok nedenlerden dolayı bu temel büyüklükler sinüsoidal özelliklerini k…
Development of semiconductor technology, the introduction of computers, smart devices and many household appliances into our lives, especially in the last 20 years, the increase in interest in renewable energy sources, the density of the population in the grid…
A microgrid is a power grid consists of distributed power generation units and loads. Microgrid is also a system that can operate in grid-connected mode and islanding (autonomous) mode. The control of distributed power generation units in microgrids is necessa…
DC-DC boost converters are usually used so as to increase voltage in battery charging of electrical vehicles, power factor correction circuits and solar photo voltaic panels etc. applications. The control of these converter types is realized with Pulse Width M…
The next generation aircraft will be operated first with hybrid technology and then with purely electric technology, just like in the automobile industry. More electric aircraft concepts today have brought about a reorganization of the generation, transmission…
This study includes the design of quadratic cascade DC/DC boost converter with PI controller. Two or more cascade boost converters have been used to increase system efficiency. Advantages of the proposed converter compared to the conventional boost converter a…
Fotovoltaik (FV) sistemler birkaç W’dan, MW’a kadar ölçeklendirilebilmesi gibi özelliklerinden dolayı en çok yaygınlaşan yenilenebilir enerji kaynağı türüdür. Bu enerji kaynağından en yüksek oranda yararlanılabilmesi maksimum güç noktasını izleyen (MPPT) dönüş…
Güç sisteminde akım ve gerilimin dalga formunun sinüsoidal formda olması gerekir. Fakat bu her zaman mümkün olmaz. Non-sinüsoidal gerilim veya elemanlar güç sisteminde harmoniklerin oluşmasına sebeb olur. Harmonikler güç sisteminde, ek ısıl kayıplara, rezona…
