In the 1990s, official land policy debates in Southern Africa have become focused on two strategies: promoting freehold land markets to replace so-called customary tenure zones and expanding ‘commercial farming’ through market mechanisms. These two strategies are expected to resolve the escalating land problems. Yet, in the guise of promoting sustainable land use, environmental care, new agricu...

Origin-destination (OD) matrices are essential for various analyses in the field of traffic planning, and they are often estimated from link flow observations. We compare strategies for allocating link flow detectors to a traffic network with respect to the quality of the estimated OD-matrix. First, an overview of allocation strategies proposed in the literature is presented. Second, we give an...

In this paper, using high order perturbative series expansion method, the critical exponents of the order parameter and susceptibility in transition from ferromagnetic to disordered phases for 1D quantum Ising model in transverse field, with ferromagnetic nearest neighbor and anti-ferromagnetic next to nearest neighbor interactions, are calculated. It is found that for small value of the frustr...

Despite encryption, you can extract a fair amount of information from VoIP traffic based on variable bit rates. Previous research shows that the language and specific phrases can be identified in this manner. DiOrio’s research looks at detecting different accents based on the encoding bit rate. Preliminary results show that the average accuracy of differentiating accent pairs is 73%, with the b...

In this paper, the relationship between the thermodynamic and historical arrows of time is studied. In the context of a simple combinatorial model, their definitions are made more precise and in particular strong versions (which are not compatible with time symmetric microscopic laws) and weak versions (which can be compatible with time symmetric microscopic laws) are given. This is part of a l...

‎In this paper we prove that a finite group $G$ having at most three‎ ‎conjugacy classes of non-normal non-abelian proper subgroups is‎ ‎always solvable except for $Gcong{rm{A_5}}$‎, ‎which extends Theorem 3.3‎ ‎in [Some sufficient conditions on the number of‎ ‎non-abelian subgroups of a finite group to be solvable‎, ‎Acta Math‎. ‎Sinica (English Series) 27 (2011) 891--896.]‎. ‎Moreover‎, ‎we s...

Monitoring approaches to consciousness claim that a mental state is conscious when it is suitably monitored. Higher-order monitoring theory makes the monitoring state and the monitored state logically independent. Same-order monitoring theory claims a constitutive, non-contingent connection between the monitoring state and the monitored state. In this paper, I articulate different versions of t...

PREDICTION IN AUTOREGRESSIVE PROCESSES C. K. ING AND C. Z. WEI National Taipei University and Academia Sinica Abstract Assume observations are generated from an infinite-order autoregressive (AR) process. Shibata (1980) considered the problem of choosing a finite-order AR model, allowing the order to become infinite as the number of observations does in order to obtain a better approximation. H...
