Considering profiles as functional variables, two control charts are proposed for their monitoring in phase II. Due to its conformity with the nature of real-world profiles, applying functional model leads to proposed control charts obtained through functional data analysis techniques with desired features. These include simplicity in calculation and possibility of using them for different prof...

Device specific power consumption information leads to a high potential for energy savings. Smart meters are currently deployed in several countries, but they are only able to track the overall consumption in domestic and commercial buildings. One promising option to gain device specific information is called Nonintrusive Load Monitoring (NILM), which can be of great use in combination with sma...

This chapter presents an agent-based approach to intelligent information dissemination in dynamic environments. We will describe a prototype agent-based system, called the Anticipator, which enables an information dissemination system to adapt to changing information needs of users and provide the users with critical information relevant to those dynamic changes. The Anticipator models the info...

BACKGROUND The measurement of blood pressure (BP) by the patient himself without strict protocols, adequate training, and validated equipment at their own household is defined as self measured blood pressure (SMBP). OBJECTIVE To evaluate the interference of the SMBP in treatment adherence and blood pressure control. METHODS The study included 57 patients, 38 in the study group (SG) and 19 i...

in some statistical process control applications, quality of a process or product can be characterized by a relationship between a response and one or more independent variables, which is typically referred to a profile. in this paper, polynomial profiles are considered to monitor processes in which there is a first order autoregressive relation between the error terms in each profile. a remedi...

in many manufacturing processes, the quality of a product is characterized by a non-linear relationship between a dependent variable and one or more independent variables. using nonlinear regression for monitoring nonlinear profiles have been proposed in the literature of profile monitoring which is faced with two problems 1) the distribution of regression coefficients in small samples is unkno...

In conventional profile monitoring problems, profiles for products or process runs are assumed to have the same length. Statistical monitoring cannot be implemented until a complete profile is obtained. However, in certain cases, a single profile may require several days to generate, so it is important to monitor the profile trajectory to detect unexpected changes during the long processing cyc...

We consider the quality of a process, which can be characterized by a simple linear Berkson profile. One existing approach for monitoring the simple linear profile and two new proposed schemes are studied for charting the simple linear Berkson profile. Simulation studies demonstrate the effectiveness and efficiency of one of the proposed monitoring schemes. In addition, a systematic diagnostic ...
