—Wireless network coding has been shown to reduce the number of transmissions by exploiting the broadcast nature of the wireless medium. Multiple packets may be encoded into a single packet when their respective next hops have enough information to decode them. Previous research has shown that packets belonging to different flows may be encoded (inter-flow(More)
Routing is one of the most challenging development issues in delay-tolerant networks (DTNs) because of lack of continuous connection. Existing routing schemes for DTNs provide best effort service, but are unable to optimize QoS and support message priority. In this paper, we present a Look-Ahead Routing and Message Scheduling approach (ALARMS) which(More)
In this paper, the problem of image fragment reassembly has been researched. The multipurpose use of the shape and texture features of fragment is introduced, and a new approach is proposed for a type of specific fragment, polygon image fragment. Since polygon image fragment has a characteristic that it has obvious corners, this approach takes advantage of(More)
Recently Vehicular Ad-Hoc Network (VANET) is becoming popular because of its promise for improving driving experience with respect to both safety and convenience concerns. One of the most important applications is to disseminate emergency notification messages to drivers in order to notify them the occurrence of an accident. The core challenge of message(More)
A new general methodology is introduced for computer-aided reassembly of the polygon image fragments. Since polygon image fragment has a characteristic that it has obvious corners, this methodology takes advantage of such characteristic, and detects the corners by Hough transform and fuzzy reasoning. Meanwhile, it computes the length of each side, compares(More)

Busulfan is a chemotherapeutic agent used to treat chronic myelogenous leukemia and other myeloproliferative disorders. Increasing evidence has demonstrated that busulfan may induce testicular dysfunction by targeting genes that are expressed in the testis. Here, we showed that spermidine/spermine N1-acetyltransferase 2 (Sat2) was present in testicular(More)
