Abstract: Lemmatization is a pre-processing stage in several natural language processing applications such as data retrieval. There are a few attempts on Setswana word lemmatization. Developed Setswana lemmatizers do not show in details where lemmatization fails to work well leading to reduced performance. This paper presents a detailed rule-based Setswana verb lemmatizer. Challenges in verb lemmatization are pointed out by word category. The overall results show that rule based Setswana verb lemmatization gives a good performance of 87%. However, reflexive verbs have a significant large percentage of exceptions

Abstract: This paper numerically investigates ad-hoc charging strategies for a Packed Bed Thermal Energy Storage System. We derive a mathematical model of the system, whose reliability is assessed through comparison with experimental measurements taken on a laboratory-scale prototype with the packed bed made of alumina particles and air being used as the heat transfer media. Then we show by numerical investigations that certain non-constant flow profiles, which are determined on the basis of a predictive mechanism, yield a more effective use of the considered sensible heat storage apparatus in comparison to the commonly adopted constant-flow charging/discharging process.
