A Matching Mechanism for Provision of Housing to the Marginalized

During this pandemic, there have been unprecedented community and local government efforts to slow down the spread of the coronavirus, and also to protect our local economies. One such effort is California's project Roomkey that provided emergency housing to over 2000 vulnerable persons but fell short of the set goal of 15,000. It is projected that the homelessness problem will only get worse after the pandemic. With that in mind, we borrow from efforts like project Roomkey and suggest a solution that looks to improve upon these efforts to efficiently assign housing to the unhoused in our communities. The pandemic, together with the project Roomkey, shed light on the underlying supply demand mismatch that presents an opportunity for a matching mechanism solution to assigning housing options to the unhoused in a way that maximizes social welfare and minimizes susceptibility to strategic manipulation. Additionally, we argue that this automated solution would cut down on the amount of funding and personnel required for the assignment of housing to unhoused persons. Our solution is not intended to replace current solutions to homeless housing assignments but rather improve upon them. We can not postpone a proper solution to homelessness anymore, the time is now as the need for an efficient solution is most dire.

A Matching Mechanism with Anticipatory Tolls for Congestion Pricing

This paper presents a matching mechanism for assigning drivers to routes where the drivers pay a toll for the marginal delay they impose on other drivers. The simple matching mechanism is derived from the RANKING algorithm for online bipartite matching proposed by Karp et al. [8]. The toll, which is anticipatory in design, is an adaption of one proposed by Dong et al. [5]. Our research proves that the matching mechanism proposed here is pareto user-optimal and can be adapted to give network optimal results for the minimizing total social cost of travel.

Introduction of a Hybrid Monitor to Cyber-Physical Systems

Computing and technology have vastly changed since the introduction of firewall technology in 1988. The internet has grown from a simple network of networks to a cyber and physical entity that encompasses the entire planet. Cyber-physical systems(CPS) now control most of the day to day operations of human civilization from autonomous cars to nuclear energy plants. While phenomenal, this growth spurt has created new security threats. These are threats that cannot be blocked by a firewall for they are not only cyber but cyber-physical. In light of these new cyber-physical threats, this text proposes a security measure that promises to enhance the security of cyber-physical systems. Using theoretical cyber, physical, and cyber-physical attack scenarios, this text will highlight the need for some sort of monitor in cyber-physical systems as an extra security measure. Additionally, this text will illustrate the efficiency of said monitor using a Shannon entropy proof, and a multiple security domain nondeducibility(MSDND) proof.
