Hand Gesture Detection & Recognition System

The project introduces an application using computer vision for Hand gesture recognition. A camera records a live video stream, from which a snapshot is taken with the help of interface. The system is trained for each type of count hand gestures (one, two, three, four, and five) at least once. After that a test gesture is given to it and the system tries to recognize it.A research was carried out on a number of algorithms that could best differentiate a hand gesture. It was found that the diagonal sum algorithm gave the highest accuracy rate. In the preprocessing phase, a self-developed algorithm removes the background of each training gesture. After that the image is converted into a binary image and the sums of all diagonal elements of the picture are taken. This sum helps us in differentiating and classifying different hand gestures.Previous systems have used data gloves or markers for input in the system. I have no such constraints for using the system. The user can give hand gestures in view of the camera naturally. A completely robust hand gesture recognition system is still under heavy research and development; the implemented system serves as an extendible foundation for future work.

Gudinnan Hathor : en studie ur metallurgiverksamhetens perspektiv som belyser auktoritära strukturer i forna Egypten

Denna studie undersöker gudinnan Hathors funktion i forna Egypten med utgångspunkt från metallurgiverksamheten som Hathor var beskyddare över. Studien undersöker vad för behov som uppstår i metallurgikontexten och hur denna kan ha påverkat och speglats i förställningar kring gudinnan Hathors funktion i forna Egypten. Studien stödjer sig på William Padens teori om religiösa Världar för att därigenom belysa hur behov i en specifik kontext kan spelgas i den Religiösa Världen. Undersökningen baseras på tolkningar av en rad olika forskningsrapporter. Dels etnografiska dokumentationer om metallurgikontexter ifrån Afrika söder om Sahara, arkeologiska utgrävningar från gruvområdet i Timna i Sinai och forskares interpretationer kring gudinnan Hathors funktion i forna Egypten. Ifrån metallurgiverksamheten studerades dels hur den äldre teknologin fungerade och hur den inverkade på religiösa föreställningar och den auktoritära strukturen i Afrika. Därtill vad för sorts belägg som finns för metallurgiverksamhet i Timna i Sinai och hur gudinnan Hathors kults närvaro i gruvområdet kom till uttryck. Dessutom studeras forskares interpretationer som rör gudinnan Hathors kults funktion, auktoritära struktur och kultens förhållande till konungen i forna Egypten. Dessa uppgifter analyserades därefter och studien visar starka indikationer på att gudinnan Hathor skapades och användes i syfte att gagna en begränsad grupps intresse i forna Egypten. Att gudinnan Hathors funktion och de offentliga festivalerna var till för att upprätthålla en auktoritär struktur och vidmakthålla smidessläktets och prästerskapets makt.

Creating Prestige and Global Networks through Conference Rituals

An international conference is a secular ritual which serves to create, recreate and shape global-wide translocal cultural sharings. Social anthropological theories and methods are used to show that, besides being an information flow junction, the international conference is a network crossroad and a way of socialising new members into aninternational research community. It is also capable of creating prestige and honour for the individual researcher,for the arranging research team, university and city. Rituals do not merely reflect the social relations or cosmology of a society, but are events that in themselves do important things through ritual forms and symbolic statements.

New Meanings to Old Rituals : The Emergence of Mourning Rituals in Shiʿite Islam

This paper will discuss the emergence of Shiʿite mourning rituals around the grave of Husayn b. ʿAli. After the killing of Husayn at Karbala’ in 61/680, a number of men in Kufa feel deep regret for their neglect to come to the help of the grand­son of the Prophet. They gather and discuss how they can best make penitence for this crime. Eventually, they decide to take to arms and go against the Umayyad army – to kill those that killed Husayn, or be killed them­selves in the attempt to find revenge for him. Thus, they are called the Penitents (Ar. Tawwābūn). On their way to the battlefield they stop at Husayn’s tomb at Karbala’, dedicat­ing themselves to remorseful prayer, crying and wailing over the fate of Husayn and their own sin. When the Penitents perform certain ritual acts, such as weeping and wailing over the death of Husayn, visiting his grave, asking for God’s mercy upon him on the Day of Judgment, demand blood revenge for him etc., they enter into already existing rituals in the pre-Islamic Arab and early Muslim context. That is, they enter into rituals that were traditionally performed at the death of a person. What is new is that the rituals that the Penitents perform have partially received a new content. As described, the rituals are performed out of loyalty towards Husayn and the family of the Prophet. The lack of loyalty in connection with the death of Husayn is conceived of as a sin that has to be atoned. Blood revenge thus be­comes not only a pure action of revenge to restore honor, but equally an expression for true religious conversion and penitence. Humphrey and Laidlaw argue that ritual actions in themselves are not bearers of meaning, but that they are filled with mean­ing by the performer. Accord­ing to them, ritual actions are apprehensible, i.e. they can be, and should be filled with meaning, and the people who perform them try to do so within the context where the ritual is performed. The story of the Penitents is a clear example of mourning rituals as actions that survive from earlier times, but that are now filled with new meaning when they are performed in a new and developing move­ment with a different ideology. In later Shiʿism, these rituals are elaborated and become a main tenet of this form of Islam.
