Recently, wafer fabrication has become more complicated and lengthened the product queue time. To ensure final product yield, engineers need to set up queue time limits for particular machines during wafer processing; we name it as “time constraints”. Time constraint problems are more serious when the time constraint is short, process is reentrant and batching. Generally, batch processing in wa...

This paper discusses an order batching formulation and heuristic solution procedure suitable for a largescale order picking situation in parallel-aisle picking systems. Order batching can decrease the total travel distance of pickers not only through reducing the number of trips, but also by shortening the length of each trip. In practice, some order picking systems retrieve 500~2000 orders per...

Commutative Supersingular Isogeny Diffie-Hellman (or CSIDH for short) is a recently-proposed post-quantum key establishment scheme that belongs to the family of isogeny-based cryptosystems. The protocol based on action an ideal class group set supersingular elliptic curves and comes with some very attractive features, e.g. ability serve as “drop-in” replacement standard curve protocol. Unfortun...

Traffic analysis is typically countered by the use of intermediary nodes, whose role is to perturb the traffic flow and thus confuse an external observer. Such intermediaries are called mixes. We address attacks that exploit the timing behaviour of TCP and other protocols and applications in low-latency anonymity networks. Intermediaries delay and reroute exchanged messages, reorder them, pad t...

Secure socket layer (SSL) is the most popular protocol to secure Internet communications. Since SSL handshake requires a large amount of computational resource, batch RSA was proposed to speedup SSL session initialization. However, the batch method is impractical since it requires a multiple of certificates. In this paper, we overcome this problem without modifying SSL protocol. To select the o...

Batching orders and routing order pickers is a commonly studied problem in many picker-to-parts warehouses. The impact of individual differences in picking skills on performance has received little attention. In this paper, we show that taking into account differences in the skills of individual pickers when assigning work has a substantial effect on total batch execution time and picker produc...
