The study aims to shed light on the conceptual framework of IOT as a modern term in the field of informatics, and determine its importance and its various applications, In addition to analyzing its contribution on the creation value for different act
ors (institutions, governments, individuals ...), Because of its investment and connection to this huge information system, Generally the IoT market revenue is expected to reach $600 B by the end of 2020
Internet of Things plays a key role in our lives today from managing airport passenger traffic, smart houses and cities to taking care of the elderly, it aims to improve life in all areas, and the technological development we are seeing has contribut
ed to a wide spread in many domains.
Platforms are the supporting software that connects everything within the Internet of things system. The platform facilitates communication, data flow, device management, and application functionality.
The Thinger.io platform is an easy-to-use platform that provides a variety of services to users. The platform enables communication of various types of devices and chipsets.
The idea was to create a personal assistant that works via voice commands to control devices connected to the Thinger.io platform remotely over the Internet in real time, The aim of adding this possibility to the platform is to make it simpler to allow anyone of any age or experience to use it to facilitate their life the way they choose, whereas The Vinus Assistant - as we called it - has the flexibility, reliability and functionality to deal with any application.
IOT sensors use the publish/subscribe model for communication to benefit from its
decoupled nature with respect to space, time, and synchronization. Because of the
heterogeneity of communicating parties, semantic decoupling is added as a fourth
di
mension. The added semantic decoupling complicates the matching process and reduces
its efficiency. The proposed algorithm clusters subscriptions and events according to topic
and performs the matching process within these clusters, which increases the throughput
by reducing the matching time . Moreover, the accuracy of matching is improved when
subscriptions must be fully approximated . This work shows the benefit of clustering, as
well as the improvement in the matching accuracy and efficiency achieved using this
approach.
يهدف هذا البحث إلى تسليط الضوء على مفهوم إنترنت الأشياء أو ما يعرف ب IoT تناولنا في بحثنا مقدمة عامة عن إنترت الأشياء, ثم انتقلنا إلى مكونات IoT بما فيها الأجهزة/الحساسات أساليب الربط بينها وبين التطبيق السحابي, البرمجيات المستخدمة لمعالجة البيانات و
وواجهات المستخدمين للتفاعل معها, ثم انتقلنا إلى الحديث عن مفهوم IoT Platforms وذكرنا منصتين شهيرتين هما Carriots, ThingWorx مع ذكر الخدمات التي تقدمها المنصتان, في القسم التالي ذكرنا العلاقة الوطيدة بين IoT وبين التطبيقات السحابية, وكيف ساعدت السحابة على انتشار المنصات بسهولة, تاليا ذكرنا مجموعة من تطبيقات IoT وتوسعنا بشرح التطبيات الطبية منها, وختاما تكلمنا عن إنترت الأشياء في عالمنا العربي.

This paper provides algebraic representation of Petri Nets model, taking
advantage that the releasing principle of Petri Nets depends on reduction process
of Monoiad of the commutative natural numbers.
(In conclusion) Finally, we provided a theore
m that explains how to make use of
algebraic properties, to simulate Petri Nets algebraically and identify the results
we will get after releasing a series of Petri Nets' transitions.
إنترنت الأشياء أضحى أكثر من شبكات سيارات أو ماكينات صنع القهو بل أصبح شبكات كبير
مترابطة مع بعضها البعض وإن أمن هذه الشبكات يؤثر بشكل مباشر أو غير مباشر على أدائها،
فهناك كثير من الناس والشركات التي تتعامل مع إنترنت الأشياء لا تعلم ماذا يحدث على
الشبكة
من عمليات تنصت وسرقة بيانات وغيرها. مع تأمين شبكات إنترنت الأشياء أصبحت هذه
القضايا تحدياا كبيراا، وبما أننا غير قادرين على إيقاف شبكات إنترنت الأشياء من النمو فإن
موضوع الأمان أصبح من الضروري جداا البحث فيه واقتراح استراتيجيات أمنية لحماية الشبكات

The world faces a number of grand challenges such as climate
change, environmental degration, energy, water and food shortages,
and public health issues. A nanometer (nm) is one-billionth of a
meter. At nanoscale (around 100 nm or less) materials
can show
marked changes in optical, magnetic, electrical, chemical and
physical properties, facts that have been known for some time but
are only recently being exploited. Such properties mean that
nanotechnology is a very exciting area and may help to find
solutions to medical, social and environmental problems which
adversely impact upon the quality of life of the people. This
research aims to highlight nanotechnology and some of their
applications, in addition to some analytical methods and equipments
used to measure the structures of nanomaterials and potential risks
when dealing with this technology. We also present the results
obtained from application of nanotechnology in the field of gas
sensors.
