Since the COVID-19 pandemic hit last year, countries locked their borders. Thus, international shipping deteriorates drastically. Simultaneously, social distancing increased need for immediate online consumption and fast home delivery. In non-digital world, products still to be shipped destination using trucks, trains, airplanes, ships. requirements volumes of goods, transport costs, external l...

This document describes how to further extend the Public Key Cryptography for Initial Authentication in Kerberos (PKINIT) extension [RFC4556] to exchange an opaque data blob which a KDC can validate to ensure that the client is currently in possession of the private key during a PKInit AS exchange.

The Windows 2000 Kerberos implementation [1, 2] uses a di erent approach to solve the Kerberos realm resolution problem than has traditionally been used by MIT Kerberos implementations. In this paper, we present the details of the two approaches and compare them. To facilitate more e ective use of the Kerberos ticket cache, we propose a new format for referral data that includes a list of alias...

Basic approaches of mobile cyber-physical systems (CPS) such like cars, trains, aeroplanes or spaceships are parts of our daily life. Mobile CPSs are embedded into a physical environment which is usually harsh and uncertain. Monitoring mobile CPSs is essential to ensure reliability and to avoid damage. Monitoring mobile CPSs presupposes knowledge about the CPS, the physical environment and the ...

The starting point for this work was: What would be the implications when systems and with them their management systems would become two orders of magnitude larger then they are today? We focus on one problem: How management agents can be automatically deployed in massive amounts (>>10) providing the infrastructure for management and control systems of large-scale virtual data center environme...

Age adjustment, using the direct method, is the application of observed age-specific rates to a standard age distribution to eliminate differences in crude rates in populations of interest that result from differences in the populations’ age distributions. This adjustment is usually done when comparing two or more populations at one point in time or one population at two or more points in time....

The high cost of IT operations has led to an intense focus on the automation of processes for IT service delivery. We take the heretical position that automation does not necessarily reduce the cost of operations since: (1) additional effort is required to deploy and maintain the automation infrastructure; (2) using the automation infrastructure requires the development of structured inputs tha...

Community detection has become a major active area of research in recent years. A plethora of relevant methods have been implemented for directed graphs. Most of them focus on the density of links, and consider the relationship between nodes as symmetric by ignoring links directionality during their clustering step, this leading to non-semantic results. This paper propose an efficient method ba...

This paper discussed the scheduling problem of outpatients in a radiology center with an emphasis on priority. To more compatibility to real-world conditions, we assume that the elapsed times in different stages to be uncertain that follow from the specific distribution function. The objective is to minimize outpatients’ total spent time in a radiology center. The problem is formulated as a fle...
