Using several existing techniques, we have ways to tolerate or mitigate packet dropping or packet modification attacks however, they do not give an idea of where the attack occurs. In this paper, we propose an intrusion detection mechanism which describes the key sharing process and how it is possible to deal with such attacks and be able to track the position of the intrusion.

The present study investigated the tensile, flexural, impact and water absorption behaviour of PALFreinforced polyester composites as a function of fibre loading, fibre length, and fibre surface modification. The tensile strength and Young's modulus of the composites were found to increase with fiber content in accordance with the rule of mixtures. The PALF polyester composites possess superior mechanical properties compared to other cellulose-based natural fibre composites. Mechanical properties of pineapple I.INTRODUCTION The development of composite materials and related design and manufacturing technologies is one of the most important advances in the history of materials. Composites are multifunctional materials having unprecedented mechanical and physical properties that can be tailored to meet the requirements of a particula...

The trays will help the patient to read, write, and have food etc. being in the wheelchair itself. The bag provided can be used to keep the urine bag (i.e. in case of a paraplegic patient) and also as a pack to keep the amenities for regular purpose. The main advantage of this Multi-Utility Stretch Chair (MUSC) as a stretcher is that the wheelchair can be converted directly to the stretcher with variable height postures and there is a detachable tray to hold the oxygen cylinder. The reclining back and front rests works on the links connected using pin joints. The entire MUSC is foldable, so the space utilization by this product is minimized. There by reducing the extra space formed by an individual wheelchair and a stretcher by acting on a single unit. The MUSC can be collapsed and folded it can be made compact for the ease of carrying, transporting. Most of the parts in the stretch chair are detachable as the demand varies with purpose of use. When MUSC is used as a wheelchair, depending on the need of the individual a detachable propelling mechanism to favor the ease of mobility can be provided. The materials used for fabricating the unit is Structural Steel which reduces the weight of the unit. The load analysis and real time load analysis was done on using ANSYS R15. The product and the results were found good. I.

Mainly our project aims on developing an independent working mechanism so that the person on the wheel doesn't require the help of a caregiver to recline the wheelchair. The present market can provide the reclining wheelchairs which require the help of a second person to recline it for the person on the wheel. This problem of all time assistance required for a paraplegic patient can be avoided by using our mechanism. Whenever a paraplegic patient requires the help of a care giver to lie down to a bed he either requires a crutches or the help of a caregiver, instead by depending on our self-reclining wheelchair (SRWC) the patient doesn't require the help of a care giver thus he himself can use the handle on the sides to recline the front and back rests. By developing SRWC we can also take into consideration that stretchers in the hospitals can be replaced by SRWC thereby reducing the space lost mainly in a government hospital of very limited space. Thus the SRWC provides a dual purpose medical support as a wheelchair as well as a stretcher. SRWC's as stretchers in the sense it can be used in simple transportation (i.e from consulting rooms to the labs or rooms concerned or to Xray rooms).Our main objective is to develop a reclining wheelchair which can also be used as an alternative for the stretchers in the hospitals.
