In certain environments like condominium complexes, couriers are only allowed to drop off their payloads at designated drop-off stations instead of delivering it directly the recipient. These regulations have become increasingly popular in condominiums during Covid-19 pandemic, part due government SOPs encouraging adoption. A partially automated delivery system using robot that deliver from rec...

Abstract The modern design and construction of buildings have led to the adoption irregular shapes which can attract large seismic forces induce stress concentrations in building itself. To investigate this fact a number research studies been carried out. This study presents review summary performance considering vertical irregularity subjected earthquake loadings. be found by using linear nonl...

Multi-storey steel buildings are usually designed with rigid connections between beams and columns or simple hinged a stiffening system. The paper focuses on the 3D structural design of multi-storey including floor slabs shear walls. method numerical modelling has been applied to investigate influence certain elements lateral stiffness building structure, when walls considered in design. Four h...

We are using causal modeling to analyze relationships between pedagogical intervention, students’ attitudes, affective states, perceptions and outcomes, based on the data from a math tutor, Wayang Outpost. The causal model generated gives interpretable multi level interrelationships within the data variables identifying direct and indirect effects among them. We observed that among the four aff...

The Parking Services program for the City of Eugene currently hires DePaul security guards to patrol downtown Eugene parking facilities in order to record incidents and deter criminal activity. This paper conducts analysis to determine the existence of a deterrent effect from increased security presence, in addition to assessing the efficacy and efficiency of Parking Servicesʼ security guard al...

We present a framework called Semantic Streams that allows users to pose declarative queries over semantic interpretations of sensor data. For example, instead of querying raw magnetometer data, the user queries whether vehicles are cars or trucks; the system decides which sensor data and which operations to use to infer the type of vehicle. The user can also place constraints on values such as...
