Spare columns are often included in memories for the purpose of allowing for repair in the presence of defective cells or bit lines. In many cases, the repair process will not use all spare columns. Schemes are proposed to exploit these unused spare columns to store additional check bits which can be used to reduce the miscorrection probability for triple errors in SEC-DED. These additional check bits increase the dimensions of the H-matrix. The increased number of 1s in the H-matrix increases not only the area overhead but also the delay of the whole system. A method is proposed in this paper to efficiently fill the extra rows of the H-matrix on the basis of similarity between the other rows. Optimization of the whole H-matrix is accomplished through logic sharing within a feasible operating time resulting in the reduced area over head and delay.

The study of NIR spectra of six commonly used plastics was done, first in air and then in water. This thesis work also contains the measurements of refractive index of plastics in air. Both the properties of plastics i.e, NIR spectra and refractive index, have given promising results for the identification of plastic types in water.

Factors such as complex environment and surface roughness induced-light scattering of the probing light limit the optical detection of these parameters in in-situ measurements, however. In this paper, a novel application of Kramers–Kronig analysis was exploited to identify both smooth and rough film-type macroplastics with unknown thickness. This method is particularly useful in the in-situ identification of unknown film-like macroplastics; although the sample is large, the ratio function is detected from an area that corresponds to the size of a MP. Therefore, it can be applied for the case of large size MPs. The validity of the method was demonstrated using transmittance data for smooth and roughened plastics given in Kanyathare et al., 2020.

Recently, the role of micro- and nanoplastics in pollution and health issues has been realized and taken seriously. In this paper, we have studied optical properties, such as NIR spectra and refractive index, of some common plastic materials and present a method and data to screen especially problematic transparent plastics with rough surface in aquatic environments. We also give an outlook of possible optical measurement methods that could be used for detection of micro- and nanoplastics.
