Ukraine
In UKRAINE, photojournalist Eddy van Wessel documents a raw account of three years of war in Ukraine through (analogue) photography and firsthand testimonies. With decades of experience covering conflict zones, he focuses on what war means for those living through it – the soldiers on the front lines, civilians sheltering in devastated towns and cities, and those forced to flee. His images capture the visible destruction and the psychological and emotional toll of prolonged violence, making this book a visual and narrative testimony with a complex and layered depiction that is reflecting on the human cost of the largest war in Europe since World War II. It explores displacement, survival, and the boundaries of humanity in times of crisis. Where does humanity end and inhumanity begin? How do individuals maintain dignity and resilience under constant threat? What does survival look like when basic needs – and life itself – are no longer guaranteed?

Modèle d'évaluation du contrôle interne pour les entreprises
Les systèmes de contrôle interne fonctionnent à différents niveaux d'efficacité dans une entité économique. Déterminer si un système de contrôle interne particulier est efficace et/ou est un jugement résultant d'une évaluation de la présence et du fonctionnement des cinq composantes - environnement de contrôle, évaluation des risques, activités de contrôle, information et communication et suivi. Des contrôles efficaces fournissent une assurance raisonnable quant à la réalisation des objectifs fixés. Il n'existe pas de système de contrôle parfait dans une structure d'entreprise. Le coût de la mise en ¿uvre et de l'insertion d'un contrôle spécifique ne doit pas dépasser le bénéfice attendu de ce contrôle. Les contrôles internes doivent réduire les risques liés aux erreurs ou irrégularités non détectées, mais la conception et la mise en place de contrôles internes efficaces n'est pas toujours une tâche simple et ne peut pas toujours être accomplie par le biais d'une série de solutions rapides. J'espère que ce livre vous aidera à expliquer les concepts de contrôle interne et vous donnera quelques idées pour améliorer les contrôles de votre service. Dr. Cem Niyazi Durmü.

Modello di valutazione del controllo interno per le aziende
I sistemi di controllo interno operano a diversi livelli di efficacia in un'entità commerciale. Determinare se un particolare sistema di controllo interno è efficace e/o è un giudizio risultante da una valutazione della presenza e del funzionamento dei cinque componenti - ambiente di controllo, valutazione del rischio, attività di controllo, informazione e comunicazione e monitoraggio. I controlli efficaci forniscono una ragionevole sicurezza riguardo al raggiungimento degli obiettivi stabiliti. Non esiste un sistema di controllo perfetto in una struttura aziendale. Il costo di implementazione e inserimento di un controllo specifico non dovrebbe superare il beneficio atteso del controllo. I controlli interni dovrebbero ridurre i rischi associati a errori o irregolarità non rilevati, ma progettare e stabilire controlli interni efficaci non è sempre un compito semplice e non sempre può essere realizzato attraverso una breve serie di soluzioni rapide. Spero che questo libro vi aiuti a spiegare i concetti di controllo interno e vi dia alcune idee per migliorare i controlli del vostro dipartimento. Dr. Cem Niyazi Durmü.

Modelo de evaluación del control interno para empresas
Los sistemas de control interno funcionan con diferentes niveles de eficacia en una entidad empresarial. Determinar si un determinado sistema de control interno es eficaz y/o es un juicio resultante de la evaluación de si los cinco componentes -entorno de control, evaluación de riesgos, actividades de control, información y comunicación y supervisión- están presentes y funcionan. Los controles eficaces proporcionan una garantía razonable sobre la consecución de los objetivos establecidos. No existe un sistema de control perfecto en una estructura empresarial. El coste de la implantación y la inserción de un control específico no debe superar el beneficio esperado del mismo. Los controles internos deben reducir los riesgos asociados a errores o irregularidades no detectados, pero el diseño y el establecimiento de controles internos eficaces no siempre es una tarea sencilla y no siempre puede lograrse mediante un conjunto de soluciones rápidas. Espero que este libro le ayude a explicar los conceptos de control interno y le dé algunas ideas para mejorar los controles de su departamento. Dr. Cem Niyazi Durmü.

An Online Earthquake Evaluation Software For R/C Buildings
Structural assessment is a very hot topic in earthquake-prone countries since the evaluation of building stock is necessary for existing aged or shady buildings, after a major earthquake, or after major seismic code changes. Many different techniques are proposed in this context, but there are very limited studies on applying assessment methods using internet-based technologies even though web-based approaches will have many advantages such as formation of a building condition database, integration with other cloud services (like GIS), implementing hardware capabilities (taking photos, voice recording, vibration measurements by accelerometers, geolocation by GPS. . . etc.), automated simple analysis and reporting, access and applicability to many users and large geographic areas, and mobilization of the process using mobile platforms (smartphones and tablets).

Internal Control Assessment Model For Companies
Internal control systems operate at different levels of effectiveness in a business entity. Determining whether a particular internal control system is effective and/or is a judgement resulting from an assessment of whether the five components - control environment, risk assessment, control activities, information and communication and monitoring- are present and functioning. Effective controls provide reasonable assurance regarding the accomplishment of established objectives. There is no such thing as a perfect control system in a business structure. The cost of implementing and inserting a specific control should not exceed the expected benefit of the control. Internal controls should reduce the risks associated with undetected errors or irregularities, but designing and establishing effective internal controls is not always a simple task and con not always be accomplished though a short set of quick fixes. I hope this book helps to explain the internal control concepts and gives you some ideas for improving your department's controls. Dr. Cem Niyazi Durmü

Structural Damage Detection by NDT and Finding Axial Loads in Cables
Damage and condition identification of existing structures using non-destructive tests is a common challenge that has been worked on for a long time. In this book, two different methods were developed to find existing force on cables as well as determine bending characteristics (EI coefficients) of beam like structures (such as bridges). With the help of the proposed algorithm, the stiffness parameters of bridges can be assessed and the location of any damage that is in the magnitude which can affect displacement behavior of system can be located. The developed methods are demonstrated using the values analytically obtained from the created models and the effectiveness of the algorithm is criticized. Furthermore, several damage scenarios on a scaled lab beam was used to test the application using real experimental data; including tests on undamaged beam (for identification) and tests on the damaged beam. Additional experiments were conducted on a cable stretched in the laboratory instrumented using a load cell to measure instantaneous axial load on the cable and compare these values against the values obtained from the developed tension measurement device. The results are compared.

Modell zur Bewertung der internen Kontrolle für Unternehmen
Interne Kontrollsysteme arbeiten in einem Unternehmen auf verschiedenen Ebenen der Wirksamkeit. Die Feststellung, ob ein bestimmtes internes Kontrollsystem wirksam ist, ist eine Beurteilung, die sich aus der Einschätzung ergibt, ob die fünf Komponenten - Kontrollumfeld, Risikobewertung, Kontrolltätigkeiten, Information und Kommunikation sowie Überwachung - vorhanden sind und funktionieren. Wirksame Kontrollen bieten hinreichende Gewähr für das Erreichen der festgelegten Ziele. Ein perfektes Kontrollsystem in einer Unternehmensstruktur gibt es nicht. Die Kosten für die Umsetzung und Einführung einer spezifischen Kontrolle sollten den erwarteten Nutzen der Kontrolle nicht übersteigen. Interne Kontrollen sollten die Risiken im Zusammenhang mit unentdeckten Fehlern oder Unregelmäßigkeiten verringern, aber die Konzeption und Einrichtung wirksamer interner Kontrollen ist nicht immer eine einfache Aufgabe und lässt sich nicht immer mit einer Reihe von Schnelllösungen bewerkstelligen. Ich hoffe, dass dieses Buch dazu beiträgt, die Konzepte der internen Kontrolle zu erläutern und Ihnen einige Ideen zur Verbesserung der Kontrollen in Ihrer Abteilung liefert. Dr. Cem Niyazi Durmus.
